This defense has given up tons of big pass plays to wide open receivers, and when they do cover the receivers they aren't able to contain mobile QBs. I was surprised UF did not attempt to throw deep more often, but that was at least partially due to the massive pass rush MSU was getting.
I look for McElroy and Mallet to have big days against MSU's D (Of course, MSU will score a lot of points on Arkansas as well). Not sure about UK and UMiss, but if they can defend the rush they will get some big plays too.
