I have four comments:
(1) I really liked the video of Hayes, including both his performance and his choice of music.
(2) Almost everyone here seems to be downright glowing about Hayes, and it seems he is recognized nationally. So WHY is he an unranked ("NR") lineman according to Scout?
(3) The Gophers are building a really solid, very deep offensive line. The problem is that a large portion of our best recruits over the past 3 years are OL. We seem to be lacking, however, in most other areas, and I hope Kill can address those areas as well. I do agree that if you have a great OL, you are tough to stop offensively, especially if you also get quality QB play. Mason built his entire partially-successful program off of offensive line blocking schemes (and not much else). Rival Wisconsin still seems to be winning largely due to dominating O-lines. But before the Gophers have a chance to become a contender in the Big Ten, we'll need more than just O-linemen.
(4) Isaac seems like an extraordinarily down-to-earth young man, as exemplified by his interview on KSTP (his slight mistake on "2 wins [last year]" aside). Impressive.
