If he can convince McVay to use a FB lead blocker on power blocked run plays then I'm all for it. Rams OC will be the ones who help incorporate McVay's plays into the weekly game plan. Sean will still call the plays but by delegating the weekly game planning load he will relieve some of the weekly workload stress. Creating these game plans mean the OC must know and understand the schematic design of the play. If Mike can tweak the designs of the run plays he can make a difference in this offense.
This is why IMO McVay's coaches have been so successful. They must have a complete understanding of McVay's concepts to build those weekly game plans. I'm hoping Mike's contributions will be in the run game. I've always contended that it's more a matter of matching the blocking scheme to the talents of the RBs. Both Akers and Williams are one cut and go type of runners. These are what you want in a power or zone blocked run scheme. A successful power run scheme requires a legit lead blocker, i.e. a FB not a WR or TE. A legit FB plays like an ILB, i.e. he attacks the LBs in the same way as the LBs attack the OL. A FB blows open the hole (normally the A gaps) not just impedes the LB. The same can be said with inside and outside zone plays. How many times have we seen an outside zone run blown up by a missed block by a WR or TE? Part of the problem is expecting them to execute while playing on the LOS. The FB given his alignment in the backfield has a much better angle to make that block. This is why we are slowly seeing the return of the FB into a lot of offenses.
