coaches say you can't, so don't sign a loi
Dear people of the internet who without fail suggest that they will contain Michigan's offense by having a linebacker or safety "spy" Denard Robinson,
Please stop saying this.
A player placed in a spying role drops into a short zone on a pass play and is tasked with running down the quarterback if he breaks contain or starts scrambling. Denard Robinson doesn't really scramble. He prefers launching deep balls into whatever coverage you've got handy. You can put a guy in a spying role if you want but it won't do much other than make your defense more predictable on passing downs.
It will not do anything to slow the Michigan run game. When Michigan runs the ball with Denard your spy is just going to be playing run defense. This is hard against Denard, I know. However, telling one of your linebackers that he should watch for potential scrambles on pass plays does not help him on non-pass plays. Michigan runs the ball over 60% of the time. Denard Robinson scrambles maybe 3% of the time.
When you post on a message board or leave a comment on a blog that says "we should spy Robinson" like you're the second friggin' guy to ever think of this—your defensive coordinator is evidently the first—you should know that God throws a six-inch-tall Japanese schoolgirl with enormous glistening innocent eyes and a Hello Kitty lunchbox into a wood chipper.
Thank you for your attention.
