Good: defense actually did pretty well, considering Raiders have a top-line offense. Wright is still bad, and Lewis is obviously someone you never want to see at safety (as soon as he came in for Webb they scored a TD on him), but everyone else either did good or average. Correa seems to get washed-out of plays waaay too easily, which was the concern coming out of college. I think Orr might actually be outplaying Mosley; he is all over the field.
Bad:
OL- we knew it was going to be bad going in, but the penalties were the biggest drive-killers.
Aiken was very bad on special teams, missing a tackle while going for the big hit (which allowed for a punt return inside our 10). I'm blanking on the other ST mistake Aiken had, but he also had that OPI and the drop at the end there (a very difficult catch though)
Trestman has to run at least once there on the final set of downs, considering West was hauling butt late in the quarter.
Moore's drops may be what makes him fail in the pros. He has the physical talent to get separation and make some nice hand catches, but he drops too many balls--you can't depend on him. He had the same problem in college.
Harbaugh's decision to decline the penalty was pretty dumb, and not just in retrospect, but in the moment. You don't give a team like Oakland a second chance at getting a first down. Of course, they might have gotten off scott-free if not for the defense jumping off-sides, which is the one thing you can't do in that situation, and they should all know this, especially Suggs.
Joe seemed to be shell-shocked a bit or something, since he wasn't stepping into his throws even when he has the ability to do so.
Wallace was dumb for his penalty--you can't give them good field position at that point in the game.
