James Jones: Thumbs Up Or Thumbs Down?

I was looking over the wide receiver stats at Football Outsiders, and noticed that Greg Jennings, James Jones, and Jordy Nelson all shot up in their rankings after feasting on the Cowboys tasty pass defense. Jennings is now at No. 16 overall, and overtook WR Donald Driver as the team's most productive receiver, while Nelson is creeping up to respectable at No. 59 overall. But Jones remains closer to the bottom than the top, with a DYAR of minus 2 and he's ranked No. 69 overall, in large part due to his 3 fumbles on the year.

Still, his low ranking seems strange since he just had his best game of the season against the Cowboys (8 rec., 123 yards, and 1 TD on 9 targets). His only bad move was the one pass he didn't catch. On 3rd and goal from the 8 yard line early in the 4th quarter, he dropped a pass across the middle that hit him right on the hands, and it would have been his 2nd TD reception of the game.

But he's been so inconsistent. He's had his best games of the season, against the Cowboys and against the Vikings (4 receptions for 107 yards), on both sides of his worst game of the season (0 receptions on 5 targets against the Jets). The Jets game was so bad that he was listed behind Nelson during the pregame introductions against the Cowboys. Is he someone you trust to start ahead of Driver (if Driver's injury lingers beyond the bye week) or will he never become anything more than a No. 3 or No. 4 receiver?
