I wrote in to the Dubcast early in the season asking if Miller was hurting the Buckeyes by being out there, and was met with a resounding "no." I stand by my belief that he was a net negative for the offense, and this article at least somewhat supports my claim.
He was a negative in blocking, not once handed the ball off on a read option out of the wildcat, and rarely got open in routes. He did show good hands though, so that was a pleasant surprise. Will be interested in seeing how he runs at the combine, as I suspect we all overrate his pure speed. I imagine he's going to be mid 4.5's rather than mid 4.4's, based on how he would occasionally get caught from behind, something you never saw from, say, Ezekiel Elliott.
