I disagree. Just because a team isn't playing well, you can't state is lack of athleticism. I give Bohannon has difficulty staying with guys, yes. It really comes down to scheming and coaching, to be honest. To blame it on that is just plucking low hanging fruit. You guys are the same people that will say a college QB going to the NFL doesn't have a very strong arm, because that is what every analyst says because it makes it sound like you know what you are talking about. Again, low hanging fruit to pick.
You can't tell me these same guys coached by Izzo to play defense wouldn't be successful. Why didn't you have Wagner on that list. He's athletic but still gets beat on defense just like the others above. All these guys would eat up any average HS player. These are the athletic guys. Cook's athletic (you point out), but, he gets beat like the others, Why? Because of bad rotation or positioning. He shouldn't front players. He should be making them play in front of him where he can disrupt them with his athleticism. It is scheming and coaching these "athletes".
