This is what you can count on - Bradshaw will get banged up if they use him that much... period.
If you are using past history as a predictor of the future (as you appear to be), than you can also count on Bradshaw playing (and playing well), despite not practicing and being on the injury report.
That being said, Bradshaw isn't in NY anymore, and I don't know if that is how this situation will play out. Does Pagano have the trust in him to go out and play on Sundays/Mondays despite not practicing much, as Coughlin seemed to? I don't know if that's the case. If it's not, and he doesn't play, this is Richardson's chance: play well, put up good numbers, continue to protect the QB, and he could re-establish himself as "the man" that everyone thought he was gonna be in Indy before last week's game. If Bradshaw doesn't play, and Richardson doesn't put up good numbers, then the time-sharing idea will gain strength.
I wasn't planning on getting involved in the #### measuring contest up thread, but in response to this - yes. In his past, Bradshaw's always played through pain until he ended up on IR around week 10 or 12. It'd be a little early for him this year to miss this week, but it also took him 9+ months to adequately recover from a procedure that had a stated 10-week recovery timeline by the physicians. That seems a little odd to me. Multiple very smart front offices passed on the guy (NYG, DEN, PIT, GB) before he finally signs for what amounts to a 1-year prove-it deal in Indy. He couldn't wrest the starting job all for himself from Vick Ballard, a guy most of us agree is a mediocre talent, even if Ballard did work hard and was a team favorite.
So with all that as the background, the team (post-Ballard injury) goes out and trades a future first rounder for Trent Richardson, a top-3 pick from the year before -- a talent that many evaluators said was the best pure talent at the RB position to enter the league since Peterson. Now, yes, Trent underperformed in Cleveland last year, but his underperforming year still accumulated 1200+ yards, 50+ receptions, and 12 TDs. Yes - compiled stats as the lead guy, but also played behind a sub-par line with a sub-par (at best) coordinator and a borderline non-existant passing game and broken ribs. His efficiency stats weren't great, but until I see him post poor efficiency metrics with an average line and a solid passing game so the defense isn't expecting him to get the ball every time, I'm not throwing in the towel on the guy.
Add all that up, and I'm quite frankly surprised people have convinced themselves that Bradshaw is the guy to own here. Some posts in this thread make it sound as if you'd rather own Bradshaw than Richardson, which seems insane to me. Given all we know (Bradshaw's offseason, training camp, and early season work + Trent's draft pedigree, acquisition cost, and production despite broken ribs and a poor situation last year) I'm expecting Trent to be the lead back and get 65-70% of the work. I'm not saying Bradshaw disappears, and he may even carry flex value the rest of the way, but I'll gladly side with Trent.
One week of data after Trent spent 3 days on the team just doesn't sway me as much as it appears to sway others.
