we had the number 1 defense for the majority of the season, dont even try to pin it on them entirely, they blew the opportunity to cement themselves as the best defense in the league to get us in the playoffs, but they are the reason we were even in contention to begin with, without the defense we may be looking at a season even worse than 2015.
early on, we had injuries, and an absolute nuthouse for a coaching staff. lord knows what the hell trestman was thinking, and marty did better but was far from what we needed. trestman deserved a good bit of blame for our early losses, harbaugh can be given a fair bit of blame for some losses, specifically oakland and any other game where we went for it on 4th down in field goal range repeatedly and failed. we had james worst starting at LT for a few weeks, we had a rookie 4th round LG starting at LT for a few weeks, our center was playing injured most of the year, our top 2 edge rushers played through season ending injuries, the cb that our defense is built on missed a considerable chunk of time(and no coincidence we got absoluely torched when he was out), our top receiver missed a few weeks, we had justin forsett for the first few weeks playing dismally and west hadnt gotten the reps to heat up, dixon was supposed to be our top back but was injured to start the season, our 3rd wr was injured and playing his first nfl reps, our qb was coming off of a torn ACL and had absolutely no time to drop back and pass and still led the league in pass attempts, we had things just really not go our way like mosley fumbling a foot away from the endzone for a touchback.
i mean seriously, it was an absolute disaster of a season and we managed to fall 1 game short of the playoffs and it appears that we really started to discover our problems and began to solve them, we got healthy on the line and kept together 1 unit for a month and they played well, we saw tons of promise from our future run game with dixon looking like a manchild out there, mike wallace has cemented himself as a legit option for us moving forward, breshad perriman showed flashes of why we drafted him and did so with limited opportunities and a laundry list of obstacles, ronnie stanley is a future pro bowl LT, joe flacco heated the hell up towards the end of the year and once again proved that he is an excellent qb when he isnt trying to throw while laying on the turf, matt judon and tavon young are studs and 2 of the biggest draft steals and fixtures on our defense moving forward, we have solved our safety problem for now, i think dean pees has proven(although many will say otherwise, disregarding that shareece wright and jerraud powers were our 2 and 3 at the end of the year) that he really could be the man for the job and that he and leslie frazier are a formidable duo, cj mosley and zach orr might be the best ILB tandem in the league. we have a LOT of reasons to feel optimistic moving forward, this season had the makings of an absolute disaster and we nearly pulled it off in the end. When it was all said and done, the 4 game slide(which happened largely due to bonehead calls, extremely unlucky plays, and injuries) and the injury of jimmy smith buried us and it was just too much to overcome for a team that honestly shouldnt have been that close to the playoffs to begin with. we overachieved based on the misfortune we faced all year, and we will be back.
