Well I'd say
If you think your team is on average better go Jones (assuming you can edit your line-up before gametime) or Bryant (assuming you can't)
If you don't (or just feel like shooting big) then go Beanie Wells cause that guy is most likely to have a really good game of the three I think (but also the most likely to get shut down)
Unless you're starting Romo at QB, then go Jones or Wells if you feel you're better on average.
