I understand what you're saying but this is the guys 3rd or 4th year and he's never done a thing. It's because he doesn't care and isn't going to sacrifice to win. They got rid of Jones purely to try and motivate him by making him the only guy but obviously it's made him even worse. He's also played with a pretty good team with a good offensive line during most of that time. Yeah, they've struggled this year but he's not just playing below average, he's been awful. He couldn't even do anything against the lions. I'm happy to pick up someone like Selvin Young, Earnest Graham, Derrick Ward or Kevin Jones off the WW. If I had unlimited spots, fine, but when there's other options out there I can't see him being worth the space unless you're dealing with a lot of injuries and desperate. If you don't have injuries you should have been looking on the WW for a better player.
Maybe I'm wrong but I think he's one of the worst starters if football and he'll be long gone out of Chicago by next year.
