Maybe this whole McGahee situation might just turn out better for Henry. RBBC seems to be very effective nowadays. Look at what it did for A.Green last year. Green rarely had 3 rushes in a row, he always took a breather and let Davenport and Fisher follow up. Yet, Green's numbers were off the charts.
This could be a win-win situation for Buffalo, not only in the running game, but also in helping the passing game, which in turn further helps the running game. Especially since McGahee is a different type of runner than Henry.
