Like I said, and it's not all on the backs just mostly, the running game HAS TO IMPROVE for the new scheme to work. It's a run based scheme.
too many style of backs each game...
they are limited because they are trying to get the rookie his touches...
if they stayed with a duo set for each game, maybe one or two can get into rhythm...
they want Coleman to be that guy to spell the rookie but why play Ty a snap here and there makes no sense...
comes down to this it is either Ty or Tevin not both tandem with MC...
I would say Tevin because he better fits this scheme and then use Ty on kick returns with Berrios on punts...
if/when Tevin gets hurt you have Ty available and if Tevin or anyone is out they have Perine to make active...
