Willis spoke with the media Saturday and sounds as driven as ever to raise his game. Last season, he was at an All-Pro level yet again, but he took on the added duties of covering tight ends and fared pretty well. Yes, he gave up a coupletight ends touchdowns to the Saints' Jimmy Graham in the playoffs, but he had tight coverage — and the 49ers won. This season, Willis is willing (no pun intended) to cover tight ends again, and this season's slate two of the league's best in Graham (Nov. 25) and New England's Rob Gronkowski (Dec. 16). Willis said he isn't paying attention to the overall picture but rather what might await him in Week 1: Green Bay's Jermichael Finley, who's sitting out the start of camp with a concussion (as reported by Finley's wife). "I know he's a good tight end," Willis said of Finley. "But we've got two of the best tight ends in the league. So every day for me, I don't get caught up in what teams we'll face, other than watching them and reading routes. "I feel if I can cover our guys – or cover them pretty well – then there shouldn't be a tight end in the league that I shouldn't be able to cover. So I just work on covering those guys when I have the opportunity." Vernon Davis and Delanie Walker represent Willis' sparing partners in practice.
