While Frey had nothing to do with recruiting Molk, he gets the bulk of the credit for developing him. Along with identifying and developing Omameh, Lewan, and Scofield that’s damn impressive.
I agree that the improvement from Huyge and Dorrestein was a notable accomplishment (both ended up solid starters who fended off younger/more talented players), but I wouldn’t give him much credit for Moosman and McAvoy. McAvoy was awful in 2008 (as was the whole OL) and benched by 2009. Moosman played in 2009 only because Molk got hurt. He was passable, but the loss of Molk was huge for that team.
