Smith: Why go anywhere else

San Francisco 49ers defensive end Justin Smith was interviewed today on a conference call.

Asked if he could make the transition to the 3-4 defense, he said, "Absolutely. In Cincinnati, we switched from a 4-3 to the 3-4 all the time. A lot of people don't know, but a lot of teams do that, depending on down and distance, the formations offenses are throwing at defenses. So I've done a lot before."

On his sack total (two) last year: "There were a lot of reasons for last year. Both me and Robert Geathers were hampered by injuries that we had with linebackers and (the) secondary, so we were forced into blitzing situations that caused us to have to pinch and penetrate and take up the gap."

He also had visits scheduled for Minnesota and, possibly, Jacksonville: "Why go on another visit, if you're going to be right back here?" he said.
