Many people had San Diego Chargers running back Ryan Mathews pegged as a first round fantasy pick coming into 2012. Even after Mathews broke his clavicle in the pre-season and it was clear he would miss the first few regular season games, plenty of poolies were still willing to take a risk. Now I'm not saying Mathews isn't a talented back, or doesn't have the potential to be a great player someday, but he simply hasn't done anything to prove it yet.

As usual, I've got some ranting to do before I get around to the pickups.

1. Another uninspiring Matt Stafford performance last week, his fourth in a row. He hasn't thrown more than one TD in a game, and he didn't throw any against the Vikings in Week 4. But look deeper – his completion rate on the season (65.9 percent) is actually higher than it was in last year's big breakout, he's still averaging 295.5 yards per game, and his three bad games have come against the Niners (the consensus best defense coming into this season), the Vikings (just beat the Niners and have as good a defensive line as anyone) and the Rams (surprisingly one of the better pass defenses in the league – eight picks and just two TDs allowed through the air). Things will get better.
