Should i start green-ellis or tashard choice or peyton hillis or torain?

i would still start Hillis. monitor his injury status closely but if hes heathy he would be my choice. Green-ellis is also a solid back. as a pats fan i watch him every week and he does put up points. the only problem there is he splits time with danny woodhead. buf is very weak against the p which would be good if green-ellis caught screen pes but unfortunately they typically go to woodhead. again, if healthy, start Hillis.
