I think PSU has the RB to get them to Indy, but their QB showed he panics at times (hell he almost gave Iowa the game when he flipped it back to his OL, that was damn close to a fumble). I wasn't overly impressed with their WR's. Their scheme is just tough to defend, but you get an athletic secondary and good LB's you can negate that pretty quick. Iowa just struggled in their man coverage (mainly on the back end of it). A lot of 3rd and longs Iowa's went man and it costed them.
I was thinking either Iowa is really good to be 1 play from beating #4. OR #4 isn't that good and is overrated. So its hard to tell judging from 1 game. A lot will be told this weekend if Iowa can win in East Lansing. Sometimes an emotional loss can spring board a team to a great run. It can also beat ya twice, which sucks.
