I'm not suggesting Bolden is the answer, but I also think he's not as bad as many think.
FWIW, career averages for rushing and catches below:
Lewis: 4.8, 10.5
Bolden: 4.4, 7.1
Other Patriots of note:
Vereen: 4.2, 9.4
Woody: 4.4, 9.9
Faulk: 4.2, 8.6
Other options:
Cadet: 3.4, 7.5
Thomas: 4.6, 8.0
Bolden hasn't had many opportunities, but he's done a pretty decent job when he has gotten the chance. He's caught 30 passes in 44 targets, catching 68% of his targets. Vereen has caught 69% of his, while the other Patriots backs were all around the 74-77% range.
And several other backs in his draft year have taken some time to get on track. Lamar Miller is still a bit inconsistent, but broke the 1,000 yard mark last season, while Ronnie Hillman was just beginning to emerge for the Broncos this season.
Again, not saying go pick up Bolden in your FF leagues or anything like that. But I think he's highly under-rated, and he's really nowhere near as bad as many seem to think.
