Patriots running back Laurence Maroney expects to be the key in the team's Wild Card game against the Ravens on Sunday. New England hasn't used Maroney much as of late. "I know how good of a back I am," the running back said. "The team knows how good of a back I am. As far as going out there to prove anything, I don't have to prove anything to anybody. I know how good I am. I'm just going to go back out there and have fun." Maroney has only carried the ball five times for 22 yards over the last two weeks, Patriots coach Bill Belichick isn't concerned about him, and he expects Maroney to perform well on Sunday. "He's gotten plenty of plays in practice," Belichick said. "He wasn't active last week against Houston but he's carried the ball plenty of times in his life and he's gotten a lot of reps out there on the practice field both last week and this week, so I'm sure he'll be ready to go. Laurence, I don't think, lacks confidence."
