How 49ers want Patrick Willis to improve

SANTA CLARA, Calif. -- Patrick Willis set a career high with six sacks last season. The four-time Pro Bowl choice has 10 sacks over the past two seasons, tied with Pittsburgh's Lawrence Timmons among NFL leaders at inside linebacker.

"He is very good and better than I thought he was in most areas," new defensive coordinator Vic Fangio said after practice Tuesday. "We need to make him a better blitzer."

Specifically, the 49ers are working with Willis to improve his technique against running backs assigned to account for blitzes. Willis is already a complete inside linebacker with no apparent weaknesses to his game. Rushing the passer generally isn't a priority at his position; most elite pass-rushing linebackers play on the outside. But the 49ers think Willis can become more dynamic, a scary thought for opposing defenses.

"I think it would complete his game, to where not only is he a good cover linebacker and he plays the run well, but he's a threat when we rush him as either the fourth or fifth guy," Fangio said. "He is behind as a blitzer from a know-how standpoint. ... He knows that and is working diligently both on and off the field."

Even the best players can get better. Pushing Willis in this area seems like a no-lose proposition for San Francisco.
