Smih has no excuses like most of the others for having a completion percentage three points below that of the league average. He completed 70 percent of his passes for the 49ers last season, so it's not as if he doesn't have the necessary accuracy.
The Chiefs have dropped some passes on Smith, particularly in recent games. The problem hasn't been as bad as with many other teams. Either way, Kansas City's passing game will continue to flounder until Smith and the Chiefs get him completing somewhere about 65 percent of his passes.
