Football Outsiders' Cover-3 is a weekly column that gives an in-depth look at three specific players or units on every single play of the previous game. This week Tamba Hali has been highlighted for his domination of Buccs big-money LT Donald Penn. "I didn't play very well," Penn told the St. Petersburg Times. "I need to go watch film and see my mistakes and fix them and see what (Hali) saw that made him play different. He played different than he did against Atlanta (in the preseason opener). I need to make sure I'm not setting up wrong. It wasn't a matter of him manhandling me. But I do need to work on some things. It's good, I think. This is what the preseason is for. And Tamba Hali, he's a good defensive end. It's not like he's some slouch. But I need to get all this out of me in the preseason so this doesn't happen again."
