The offensive line is the #1 concern this Spring and losing the position coach is a tremendous blow. Moreover, the entire spring relies on the offensive line coming through. If the offensive line is in shambles then it become impossible to evaluate both the other offensive players and the opposing defensive players.
On a more positive note, Willingham had a nice quote about JR Hasty on Dawgman.com "J.R. makes yardage," Willingham said. "Talk about not being a sprint champion or this or that, and we take up so much time talking about what they aren't we lose focus on what they do. He gains yardage and understands how to do that, and that's a great quality to have."
