I don't really see that happening. This really is what the issue boils down to with Barber.
Everyone who thinks he is top-5 material is relying on him increasing his workload dramatically. Last year as they increased his workload his YPC dropped off significantly, from 5.4 in games 1-8 to 4.2 in games 9-16. Additionally, his YPC on carries 16-20 was 2.0. The Cowboys just don't benefit from him getting over 15 carries a game. As far as receptions go, last season he had a career high, but this season they have a better receiving option out of the backfield in Jones, so expecting Barber to see 30-40 catches again just isn't reasonable.
Also to note, he only had 10 rushing TDs last season, despite the increased workload. Partially this was due to the Cowboys passing more in the red zone. But to count on him having enough TDs to offset his lower number of carries this year is risky.
He's fun to watch, a tough player, a hard worker - but he's not a top-5 RB. The FBG hype is just way too high on him right now.
