Maroney was running very tough, and seemed to go forward for a yard or two extra after contact on most carries. He also broke a few tackles to gain extra yards, and faked Reggie Nelson right out of his shoes. Laurence was bouncing it outside very effectively when there wasn't any holes, and used his top level speed (for a RB) to gain a nice amount of yards.
Really, it was among his more complete games as a player, especially considering he recorded two receptions as well.
According to the NBC Sports report I've looked at, Maroney gained 122 yards rushing and 40 yards receiving, with 1 TD. Whenever a RB gains 162 total offensive yards he's had a very good game, especially against the Jags in the playoffs.
