I tried to list as many things that will change next season that we are sure of, since we don't know who the team will draft I left that out as an option, obviously we're all excited about a new influx of talent from the draft in a very deep class with a lot of picks.
Personally I'm torn, I love Kaepernick and I think of him as the LeBron of QBs in terms of his physical talent/potential. I'm also very excited for Lattimore, it's time to start rotating the RB position and I think Latt could take our run game to the next level while finally keeping Gore fresh for the playoffs. Tank IMO is a future star and you can never have too many pass rushers.
The loss of Culliver I think was underestimated or at least it wasn't talked about much during the season, he was on his way to being a starter and potential star, our DB needs some help and it would be huge if he can pick up where he left off. Like everyone I'm sick of Goodwin, glad he's gone, thanks for your service but I'm looking forward to Kilgore hoping he can improve the center spot and the rest of the OL as a whole. And of course, I love Bowman and I hope he's back before mid-season and returns to pre-injury form.
