Hairston (6-foot-7, 333 pounds) was a three-year starter with the size and strength to be a strong right tackle in the NFL. Although he played the left side at Clemson, his mediocre footwork will likely force him to the right once he goes pro. He missed two games due to a knee injury as a senior, but durability is no real concern. He is likely a fourth-round pick.
Grant (6-foot-6, 327 pounds), on the other hand, has major durability issues. He lost most of his first two seasons to knee injuries and started just five games in 2008 after hurting his hand. He was healthy the last two seasons, though, and won second team All-Pac 10 honors on both occasions (playing right tackle in 2009 and left tackle in 2010). He figures to be available on the third day of the draft.

Gantt (6-foot-5, 260 pounds) caught 64 passes for 951 yards and nine touchdowns over his final three seasons at Michigan State. He is a solid two-way tight end who is also a positive presence on special teams and in the clubhouse. A late-round prospect, he could help offset the potential loss of Randy McMichael.
Walls (6-foot-0, 190 pounds) finished his Fighting Irish career with 104 tackles, 20 pass breakups and five interceptions, including three as a senior. While he has plenty of experience patrolling the secondary, he would likely be targeted late in the draft for his ability to cover kicks, something he did well throughout his career.
