One of the key decisions coaches will make this offseason will be deciding if Leonard Davis remains at left tackle or should move to guard. Coach Dennis Green has been adamant that Davis has the skills to play left tackle, and has pointed out several times that such a high pick (second overall in 2001) should not be used on a guard. But Davis started his career at guard and played much better at that spot than he has at tackle. He's been average at tackle, but he was a devastating guard, especially in the run game. By moving Davis to guard, the Cardinals would solidify a week spot, strengthening the interior of the line. The downside of such a move, however, is that the club would have to find a left tackle in free agency or the draft. There's no one on the roster capable of playing there. . . .
