Your timing is incredible. I just read a guy's take on this who blogs on the Boys. He raised in interesting set of options on how this could turn out. The Cliff Notes are:
The offense runs about 60 plays on average the last two years.
The offense on average splits run/pass about 48/52% respectively.
These are nearly exact to the 2008 Giants offensive split on both categories. The similarities between Barber and Jacobs can't be ignored. Ward and Jones is a bit of a stretch but the speed is there. Both Jacobs and Ward registered 1k yards on about 14 carries/game.
Jerry Jones mentioned twice how Felix Jones (no relation) will be integrated into the system both in running and especially in passing situations.
Felix Jones' game is comparable to a young Tiki Barber.
So the potential of having an identical split in carries for Barber and Jones to Jacobs/Ward of 2008 is likely. Jones' talent is greater than Ward so it is also possible that he is integrated more in the passing game, maybe 5-8 catches per game.
So take that for what it's worth but I like the analogy of re-creating the 2008 Giants runningback situations with Choice filling the role of Bradshaw. The Tiki comparison is a bit of a stretch at this point in Jones' career. He saw Jones slowly moving Barber aside like Tiki did to Jiggles Dayne back in 2000.
