I would have cut Rawls and Hayes to get Isaac in. The guy is a beats with vision, neither which the two mention have. A solid class built for B1G Ten play!
Hayes should consider moving to the slot... Rawls could be an okay power back behind a strong OL, but I fully expect Smith and Green to pass him... Shallman will probably end up as an H Back/TE, and Fitz could be a change of pace back. Drake Johnson might be a lifer on special teams, but we'll see...
