Those are the big things. Pitching is just so much better when you can't pinpoint the location. I still believe hitting is the biggest improvement of all in 2K11. The hit variety is a huge improvement. The fact you can actually make errors now is good although the default settings and stat recording are weak. Errors are not being recorded properly. I've seen a misplayed ball by the SS not counted as an error. Any throw that pulls the first basemen off the bag is not recorded as an error. Unless that ball sails over his head they won't charge the player with an error.
I don't see enough of an improvement in the AI department imo. Starters are pulled too soon and some relievers are left in too long. Base running AI is weak and my biggest complaint is the cpu not sending a runner home that's on 3rd with ground balls to the right side. Way too conservative in that situation. I haven't played enough national league games to see the bad pitcher and pinch hitting management but it's been talked about quite a bit.
I will disagree about the pitcher covering first base being a problem. I haven't seen this problem at all. They cover first on grounders to first and on the 3-6-1 double play.
