NFL.com had him as a third round pick, comp being Dion Dawkins from Buffalo. His biggest flaw was footwork/balance.
"Overview
Walker possesses enticing power and measurables but has issues that could be challenging to correct if he stays at tackle. Ohio State defenders were able to burn up his outside edge, which creates concern about his pass pro range, but it can be hard to beat his anchor with pure power. He has issues playing beyond his base, creating chronic over-extension that will be exploited by skilled NFL rush talent. He's capable as a run blocker and should keep getting better with more hand work. Walker projects as a right tackle on the next level but might move inside to guard if his range and balance in pass sets aren't up to par.
