On average, MBIII rushed the ball 12.75 times a game. I don't see that number dropping. Conceivably, as a starter, he should be carrying the ball between 18-20 times per game. He also averaged 2.75 receptions per game. That number should stay about the same with Felix getting some of those dump off passes, too.
Strictly doing the math, if MBIII does get the ball about 20 times a game, that would equate to 1,536 yards if he's able to maintain the 4.8 ypa he averaged last year. Again, all of this is hypothetical.
But, think about last year. Do you guys really think teams game planned against JuJo? Possibly early in the season, but after the first 3-4 games, the talk around the league was that Barber was the better back and all the pundits didn't understand why the Boys stuck with Jones. IMHO, other teams knew Barber was the bread and butter of the running game, but he was the unstoppable force.
I'll take anything 1,200 yds and above with 15+ TDs (rushing and receiving). I guess another factor we would have to look at is whether or not the Boys will be playing on a shorter field this year IF our return game is what everyone is hoping.
