Tough to say... If it was full 1pt/rec I'd say you'd be reaching even at 36.
.5PPR and I would probably avoid him at the 25 slot. Let the other guys reach for 2-down RB's and think about guys like DMC/Bradshaw/Felix who will probably average an extra 2pts per game due to the 3rd down dumpoffs that Blount probably won't get.
He'll probably be there at 36. I drafted him there in my PPR league and I don't regret it. Even if he isn't there on 3rd downs a lot he can still be a solid RB2 I think. Michael Turner 2.0 IMO. And he definitely has some upside if his offense has improved this year.
I would say 25, if he is there. No way he lasts until 36 in normal leagues but I just rechecked your initial post and saw 2 QB league so I'd say he might be there at 36 but if you really want him grab him at 25. I saw him as him as high as #7 RB.
