I'd do it.
Woodhead is like having Faulk on your team; he's a low end flex option who'll catch a few passes and maybe score, but he'll be doing it on your bench. Nothing is going to change that will propel his value significantly, as the Pats always use 2-3 backs.
Compare that to Wards situation. Right now, his value is arguably a little lower than Woodhead's, but if Arian Foster goes down you'll have a star. Has three touchdowns this year already on only 18 carries, along with a ridiculous 143 yards.
Big time sleeper.
