Hack, Sacca, and Allar we the only no-ceiling QBs we have ever recruited. Sacca was doubly afflicted by a premature starting role but he had a rifle arm and could run. Hack really needed BOB for his development but like David Carr, he couldn't handle the lack of pass protection. IMHO, Hack deserves respect because he came to us in a dark hour, and he wanted to be a Lion. Both he and Sacca vindicated Joe's philosophy of bringing them along patiently in his program. Joe was able to do that with Blackledge and he exceeded expectations. But if you look at him on the YouTube machine you can see his limits that were compensated by the talent on the other end of his throws which is why I don't lump him in with Sacca and Hack. From a pure talent perspective, its Sacca, Hack and Allar in Tier 1, Blackledge, Robinson, Fusina, Number #9, Clifford, Shuman and Collins in Tier 2, Richardson, Burkhart, Clark, Morelli, Huffnagle and Zack in Tier 3. Tier 3 guys are good QBs but and were able to compensate for their deficiencies. The one guy I wanted to see develop was Tom Bill. His 42-7 win against VA before his tenure went off the rails was a great night to own a television machine.
