Red Sox closer Jonathan Papelbon realizes that the team's bullpen looks good on paper, but claims that they'll have to prove their worth this season.

"I know on paper we look really good and we look like we have a lot of firepower in that bullpen," Papelbon said.

"But we looked really good on paper last year. We've got a lot of things to prove. It's not just, throw a bunch of names out there and expect to win. We've got a lot of things to work on and a lot of things to prove."
