Three keys for a 49ers’ victory against the Cardinals Amidst a

five-game stretch where the 49ers play the Chiefs Youth Alfred Morris Jersey , Chargers, Packers and Rams, the most winnable game is this Sunday against the Cardinals. Arizona comes into San Francisco winless on the season, with rookie quarterback Josh Rosen making his second start. On the other sideline, quarterback C.J. Beathard suits up as the starter for the second straight week after Jimmy Garoppolo went down for the season. Both teams are trying to find their footing after rough patches to start the season. Kyle Shanahan possesses the better roster and more experienced quarterback, so it’s time for the 49ers to go out and be the better team on Sunday. If they’re going to be successful on Sunday, here’s where San Francisco should start.1. RB Matt Breida must have a season-high in rushing attemptsWhile 49ers’ running back Matt Breida is third in rushing yards in the NFL, he’s only attempted 11, 11, 10, nine rushes in the 49ers’ four games. What’s awaiting Breida and the 49ers’ rushing attack on Sunday? Oh, only the third-worst rushing defense in the NFL in the Cardinals. Arizona has given up 565 yards on the ground, just slightly ahead New England and Detroit.Week 1 vs. Washington, running back Adrian Peterson rushed for 96 yards and one touchdown against Arizona. Last week, Seahawks’ running back Mike Davis rushed for 101 yards on the ground and two touchdowns Cheap Solomon Thomas Jersey , helping pave the way for a victory. So the 49ers aren’t going up against the ‘85 Bears on Sunday. Other than Rams’ Todd Gurley II, Matt Breida’s likely the most talented running back that the Cardinals’ defense will be facing up till now. The second-year running back is averaging 7.6 yards per attempt on the ground, leading the NFL in that category. If San Francisco can feed Breida the ball at least 15 times, then they’ll be able to move the ball, while keeping Rosen and the Cardinals’ offense — and the 49ers’ shaky defense — off the field. If Breida finishes the game with at least 100 rushing yards and 15 attempts, the chances of a 49ers’ victory is pretty high.2. Cardinals’ WR Larry Fitzgerald needs to have a quiet afternoonDespite various ailments, it looks like veteran wideout Larry Fitzgerald is going to suit up on Sunday, much to the disappointment of 49ers’ defenders. The Cardinals’ No. 1 receiver has absolutely torched San Francisco in years past.Last season, Fitzgerald had 12 catches for 132 yards in one game, while he hauled in six catches, 81 yards and a touchdown in the other matchup. Two seasons ago, the Cardinals’ receiver had 19 catches for 200 yards and two touchdowns. Historically, Fitzgerald has been a thorn in the 49ers’ side and he has a chance to be a problem again. Rosen is known to be an accurate passer and nothing helps a young quarterback like a large target. San Francisco is likely going to be without corner Richard Sherman, leaving either Ahkello Witherspoon, Jimmie Ward or Greg Mabin on duty. The trio of corners will need to slow down Fitzgerald Cheap DeForest Buckner Jersey , otherwise it could be a long afternoon for the 49ers’ defense.3. 49ers need to get off the field on third downsWell, duh Akash. Obviously, the 49ers’ defense needs to get stops on third downs and force the Cardinals’ offense off the field, this is mostly common sense. Let’s add some numbers to it, to spice it up.Till this point in the season, Arizona’s offense has been the fourth-worst at converting third downs, only moving the chains 29 percent in a third-down situation. That’s only ahead of Dallas, Seattle and Buffalo.On the flip side, the 49ers have been middle of the pack defending on third down. Their opponents are nearly converting 43 percent of the time — a number that’s not good enough on Sunday. They’re playing an offense that’s struggling on third down and they’re going to need to get off the field when they can. San Francisco should — key word should — come away with the win on Sunday. They are the more talented team, playing at home and if they are to prove that this rebuild is on the right track, it starts Sunday. Joe Fann had a really interesting article on Kyle Juszczyk this week, featuring this intriguing quote: Not just a tight end — Juice was a two-time All American at Harvard. But he had no chance to play that position in the NFL, despite 22 receiving touchdowns in college, because he’s 6’ 1”.Fullbacks are disappearing from the NFL, because GMs don’t want to give a precious roster slot to someone unlikely to touch the ball. The job is being divvied up between running backs (5’9” to 6’2”) and tight ends (6’4 to 6’7”) http://www.49erscheapstore.com/k_waun-williams-jersey-cheap , but blocking is a secondary skill at both positions. “Move” tight ends — i.e. big guys who can’t block — are increasingly common, and no one expects an RB to lead block on running plays. Running backs are supposed to protect the quarterback in passing situations (third down) while providing a check down receiving option, but again neither skill is their primary job requirement and a lot of them aren’t that good at one or both of them.Because of his height, Juszczyk is a “tweener,” in between the ideal size for two different positions, and NFL talent scouts hate tweeners. To be fair, a lot of tweeners who were great in college don’t cut it in the pros, because size + speed is a real thing, Sometimes they just get pushed around.Juszczyk got lucky because Kyle Shanahan, and his mentor Gary Kubiak — the OC at Baltimore when they first started Juice in 2014 — realized that fullback is kind of a tweener position these days, and the Harvard kid fits it perfectly. He’s tough enough to lead block on runs, quick and mobile enough to pass block, and flexible enough to line up at any pass-eligible position. (He’s even the team’s emergency quarterback.)But most GMs couldn‘t see beyond his (lack of) height. Juice has 255 yards receiving this year, more than WRs Martavis Bryant, Laquon Treadwell or Doug Baldwin Youth Richard Sherman Jersey , while blocking better than any of them. He has played almost two-thirds of the Niners’ snaps and rivals Marquise Goodwin and Matt Breida for explosion play potential, even as he personally springs Breida for his big runs with key blocks at the second level. But height-bias nearly kept him out of the league altogether.This is even more of an issue at quarterback, where college prospects 6’2” or less are routinely dismissed (except for the odd Drew Brees, Russell Wilson, or Nick Mullens who sneaks through and establishes himself as an NFL superstar).Again, these personnel evaluators are not crazy. Height is a real thing for QBs, When I was covering Michael Vick in Philly, there were many situations where he just literally couldn’t see over the various linemen and ran outside the pocket, not because of “happy feet” but just to see who was open.My theory is that some of the heroic, shorter college quarterbacks — like Johnny Manziel or Vernon Adams, Jr. — catch our eye because their size forces them to take wild chances. When those pay off, it’s impossible not to get excited. But “hanging on for dear life” in college turns into “just getting smothered” in the pros, where everyone is yet bigger, stronger and faster.But height is not the only thing that makes a QB good. (Just ask Brock Osweiler.) Niners fans are well aware that the abilities to read defenses, find open receivers Cheap Dante Pettis Jersey , throw with a quick motion, and deliver the ball accurately are at least as important as stature. How many potentially great quarterbacks never get a chance — or are converted to wide receiver, where 6’2” is big —because of rigid conceptions about height, while absolute stiffs like Christian Hackenberg get chance after chance?If Jimmy Garoppolo was 6’4”, he probably would never have been a backup quarterback and fallen into the 49ers clutches. Some really bad team would have drafted him in the top 10, and he’d be the injury-addled QB for Tampa Bay, or someone like that.The situation is a shame, but it’s also an opportunity for GMs and coaches able to see past the trite clich茅s of NFL size requirements. The Niners might have not one, but two great quarterbacks — and an all time great fullback — on their roster right now because Lynch and Shanahan don’t share the league’s blind bias against short players.
