Devontae Booker - didn't do well with his first opportunity, lost kubiak, cj anderson back, and they could draft a back. Would be happy to get a second for him.
Derrick Henry - top 10 dynasty rb. Don't sell for less than elite value.
Jordan Howard - would gladly sell for full price, if you can get it. Howard plus something could get you david johnson or bell, or you might get multiple firsts for him. Otherwise hold.
Mark Ingram - if there's any chance he's not with payton next year you have to hold for now. His value probably won't go down this offseason but it might go way up.
Eddie Lacy - all depends on what you can get for him. I would buy or sell depending on the price. He's probably worth a mid/late second in reality - a hit or miss guy with a huge distance between his floor and ceiling.
Dion Lewis - again, depends on the price. If you can get starting rb in new england price for him, do it. If you can get him for cheap flyer on an injury prone one hit wonder who disappointed last year, do it. The spread on his value is going to be pretty wide depending on the league
Spencer Ware - i would rather sell than buy right now. Since week 7 vs the saints, he had one game with a touchdown (two tds at atlanta) and no games with 100 total yards. His season totals look ok but he had 777 total yards and 3 tds in the first 6 games and 591 total yards and 2 tds in his last 8. That's a drop from 121 yards and .5 tds per game to 74 yards and .25 tds per game. Sell before people figure that out.
