I would flip them, but really not going to make much of a difference if they are getting the same amount of touches.
to me yes Rico better early with fresh OL, can hit the holes faster get a yard or 2 more but later in games Zeke against a tired D etc can be more effective. hey that's my observation... i'm not saying i'm right it's just something i think they should try more... i mean it drives me crazy they did it with tony pollard last year rico should have got he TP snaps and TP used as a cleanup IMHO,..
