I would say it is Clark's job to lose.
If he's displaced, my money would be on Pyne. Just based on experience. Especially if there is no spring. Pyne lacks ideal size, to say the least, but he's a very good athlete. Actually reminds me of a quicker Book, with maybe a little better arm strength. And I think some people don't realize that Pyne held offers from Alabama, Oklahoma, Michigan, Penn State, and a slew of others. I really like Buchner as a recruit too, though . . .he has better overall physical tools.
