For what it's worth Rutgers DID run a 2-back set the majority of the time this season. They have actually used a fullback for a few years there.
I don't care if he has a 5 back backfield, here's what cocerns me: According to ESPN: Rutgers ranked toward the bottom half of the Big East stats in scoring offense, total offense, rushing offense and passing offense. It ranked worse in every category but rushing offense than a year ago. Rutgers scored a total of 33 points in its final three Big East games -- the last two losses. Had Rutgers been able to find any semblance of consistency on offense in losses to Pitt and Louisville, it would have gone to the BCS.
Brock needs a strong, innovative OC. Let him be a CEO.
