Baker is not terrible, IMO. I don't think he's great but SF is a lot like the CLE team where he was at his best: run the ball, make a few accurate throws, play defense.
Purdy is going to get hurt standing in there and taking shots, IMO.
Love the kid's courage, but there is a reason Brady drops into the fetal position the second pressure gets close. By December half the other teams QBs are out.
