Walker and Roland did a terrible job of tackling McAnderson (and Sharp on one or two plays)
Campbell having to play DE instead of OLB, hurt our D, but i understand that Ian would have had some difficulty playing out in space in the flat.
Biggest play that no one talks about is ......
Late in 2nd quarter when Reesing got sacked and fumbled. The ball went awkwardly backwards and went right to a ku OL who was on the ground. If that ball goes straight down (like most fumbles on QB sacks do), then Ian recovers it and if he scoops it up, he would have had some serious running around as no one was around.
