Given all the guys who missed most or all of training camp due to holdouts or injuries (Trent, Aiyuk, CMC, Hufanga, Greenlaw, Pearsall) and the possible Super Bowl hangover, there's a good chance the Niners start the season slowly.
I hope it's not the case, but there's a good chance this is a down season. And after this one (when Brock gets paid) there are going to have to be some very tough moves made due to the salary cap.
This is probably Shanahan's last best chance at a title. I hope it doesn't get detailed early.
