Okay, I've never seen him play and I'm sure he's very skilled, but the article said two things that made me not really think we missed on a big time recruit: 1) He's 5'9" and 2) He's more dangerous as a runner.
First, our over 6ft QBs often get their passes batted down, and second, TH is built like a linebacker and still got injured last year. I doubt Covey would survive as a running QB in D1 if Hill had trouble with it.
