I think we just go with the hot hand. The Eagles were very effective in shutting down Ray Rice (7 carries for 8 yards) and Willis McGahee (8 carries for 7 yards). Rice essentially has the same running style as Willis, good quickness and vision, with the ability to bounce it out to the corner. Both guys are patient runner.
When looking at the Eagles front-four, they have smaller, quicker defensive linemen that are good at jumping gaps. In other words, there was no time to let holes develop for they were closing quick. Cam Cameron made a nice adjustment and shifted to a straight ahead power run game, which let our offensive line overpower the weaker Eagles line. Throw in a 260-pound straight ahead runner, and it was simply a good matchup for the Ravens.
Even though I do agree that McGahee is probably hurting, football is all about matchups and today Le'Ron McClain was simply the better matchup than Rice or Willis.
