When Shafer got hired, a lot of us expressed the opinion that his tenure was going to be defined by his choice of selection at OC. Clearly, that was his blind spot [despite him being a QB in college]. He chose poorly from the jump, hiring a career position coach to be his OC [yes, I know that McF##kit was an OC for 1 year prior to coming to SU, sandwiched around numerous stints as a WR coach].
I actually believe that Lester had potential, and might have worked out if given enough time. But as predicted up front, Shafer's tenure was defined by the selection he made at OC.
And I say that fully acknowledging that Shafer was a class act, and a heckuva role model. He just wasn't head coaching material -- exhibit A of the Peter Principle.
