Who the hell cares about the total passing yards in a game? As if this tells you how well a QB is, or isn't, playing? If you really want to look at stats at least pick one that has a little more meaning, like yards per attempt. JP is averaging 6.7 yards per attempt, which is middle of the road for NFL starters (ranked 15th in the league). He is ahead of such young signal callers as Grossman, Leinart, Manning, A. Smith. V. Young and Gradkowski. In fact the only young QBs who are better than Losman in this stat are Romo (who actually leads the entire league), Rothlesburger (who leads the league in INTs) and Rivers.
All in all Losman's numbers look pretty good, but not great.
