the 2018 season and they have begun their work to prepare for 2019 free agency and the NFL draft. The coaches and scouts are back from a week in Mobile Jimmy Garoppolo Jersey , Alabama at the Senior Bowl, but there is plenty more to be done as they get ready to build on a disappointing 2018 campaign. We’ll be breaking down plenty of what that means, but in the meantime, we wanted to take a look back at the season that was for the 49ers.Jimmy Garoppolo’s injury sent things south, but there is plenty still to assess. We are going to take a look at every notable addition and provide a forum for grading how that signing, trade, or draft pick worked out.Marcell Harris, safetyHow acquired: Drafted in the sixth round (91845th overall)Earlier this month, we put together a poll grading rookie cornerback Tarvarius Moore. Some suggested it should include a grade for incomplete, but I figured he got a full season of special teams, so there was at least something on which to base his grade.I decided to go with an incomplete for Harris, and change up the poll. Instead of grading his first year, I decided to ask for projections in year two. Specifically, what will his role be in 2019 when the Week 13 season arrives. That will be roughly the first week of December, so ideally it would not simply be garbage time in the season at that point like Week 17 may or may not be.The 49ers entered the season with the hope of a starting safety duo featuring Adrian Colbert at free safety and Jaquiski Tartt at strong safety. Injuries were a problem up and down the roster, and outside of the quarterback position, it was felt most at safety. The team went through eight safety combinations last season. There is nothing great about that, but one positive was a chance to see a host of different players get some opportunities. D.J. Reed got some time at free safety and slot corner, and Marcell Harris got a chance to close out the season as the starting strong safety.Harris entered the NFL coming off a 2017 torn Achilles that cost him his final season at Florida. The timeline put him on track to return for the start for the 2018 season, but a hamstring season put him on IR to open the season. The 49ers put him on after final cuts Mike McGlinchey Jersey , rather than before, thus opening the door for an in-season return. Harris did in fact return, making his debut in Week 9. He played six defensive snaps and 15 special teams snaps. He followed that up with 18 special teams snaps before the team’s bye week. Coming out of the bye in Week 12, he grabbed eight defensive snaps, but injuries created an opportunity. Free safety Jimmie Ward went on IR and Jaquiski Tartt moved over to that role, opening up the strong safety role for Harris. Tartt got injured the next week, and Antone Exum replaced him at free safety. Tartt went on to finish out the season as the starting strong safety.It was five weeks of ups and downs you would expect from a rookie. Kyle Shanahan and Robert Saleh both acknowledged that Harris looked like a player who had missed significant time. Saleh said he needed to clean things up after his first start, but that he expected the biggest growth could come from his first start to his second start. He showed some improvement the next week, and as the season closed out, we saw plenty to like and plenty to clean up. About what you’d expect from a rookie with potential.Shanahan said that Harris will compete for a starting role in 2019. We could see the 49ers head into 2019 training camp with Adrian Colbert and Jaquiski Tartt once again lined up to start at the two safety positions. The 49ers would bring in Earl Thomas to compete with Colbert, or could find a player in the draft. For strong safety, however, my guess is Tartt and Harris will be the prime competitors. And while one will lose out on the starting job, I suspect one will get significant playing time in a rotational role like a money-backer we see some teams use.Whether Harris starting or in a key reserve role, it will depend on him building on those five starts heading into the offseason. Shanahan said he loves Harris’ mindset, in that he does not hesitate. He will be wrong at times, but more experience will improve that. This offseason is the first step in building on that initial opportunity. What will he make of it? We have another set of playoff games for Sunday. Things start with the Los Angeles Chargers traveling to face the New England Patriots (yes, the Patriots are back in the playoffs again). The game kicks off at 10:05 a.m. PT on CBS, with Jim Nantz and Tony Romo in the booth. Tracy Wolfson will be on the sideline.Once again, I’m eating some crow. I said Dee Ford Jersey , “The Chargers won’t be good this year [direct quote].” Well, they advanced to the AFC divisional last week after beating the Baltimore Ravens. It probably was donejust to further grind into me how wrong I was. They not only are advancing, but looked good in their win against the Ravens, who were surprising people late with their retooled offense. Thanks to the AFC East being inconsistent yet again, the New England Patriots are in the playoffs and coming off their first round bye. Tom Brady gets a year older, but the Patriots just keep going like he was in his second year. Despite their status as a No. 2 seed, all four of the Patriots’ losses have come against teams not in the playoffs. All of them on the road. Well, the Patriots get home field advantage so that will help them out. New England is a four point favorite, with the largest percentage of public money on LA. It brought the spread down from five to four, and continues to come in. Normally sportsbooks are rooting against New England, but that’s not going to be the case this weekend. The Patriots may be the No. 2 seed, but when they looked off, they have been very off. I think the Chargers will manage a win in the final seconds to keep the Patriots out of the AFC Championship—and the Super Bowl—for the upteenth time.
