Brad Childress is the difference this year.
As OC in Philly, he put Westbrook in situations where he'd succeed and perform.
He'll do similar things with CTaylor this year.
Childress as OC

Childress as HC
If you're looking at Chester Taylor with "starting all season" in mind... I think "poor man's Michael Pittman"
And without straying off-topic about Deuce, you're forgetting that Bush will be half a receiver, and the other half a 3DB.
Back on topic though, how can you begin to rationalize his 3.07 ADP??
You'd be passing on a top tier WR in a year with a big hole between the goods and the okays.
Go look at his stat-lines.... if he was any good, those numbers would look a lot better as a 3DB.
a guy like LaMont Jordan or Thomas Jones going to a new team, they showed they were capable of being every-down solid backs.... Chester Taylor hasn't shown me anything... and looking at his splits after watching him so far in his career makes me think you dozen or so guys drinking the kool-aid are
