He has some value. Chicago is an improving team, not a poor one. Robinson has got great size and speed and is legit. And the Bears offense is fantasy-friendly. Your point that Jim Miller was productive in it last year proves its worthiness.
Players are certainly out to make more money so they at least try to turn it up a notch.
Otherwise, don't bother. Some have higher values than others. Check tomorrow's Pig Skinny for rookie reviews. I was thinking about Fred Taylor, but I am concerned about Jacksonville's offensive line. Taylor's speed and pass catching ability allow him to produce with little amounts of space.
