How good would Adrian Peterson be if he had the offensive line of the Rams?

I am not saying Peterson is a bad running back in fact i put him in the top 5. But i mean take a glimse back into time. Steve Hutchinson played for the Seahawks with Shaun Alexander. One of the best running backs a few years ago. But oh wait. Hutchinson goes to the VIKINGS and things go downhill. Shaun Alexander gets destroyed in the backfield because Hutschinson was gone. What about Priest Holmes. He was barely anyone on the ravens. All of a sudden he goes to the CHEIFS who had the best O-LINE and priest was one of the BEST. I mean daunte hall was returning kicks on everyone with that blocking. Goes to the rams and then a no body. My point is that Peterson is good but HOW GOOD? He fumbles a lot. What if a Steven Jackson, or Clinton Portis, Or Brian Westbrook, or Willie Parker had the Vikings Beast offensive line? And Peterson was sent to the rams. How good would peterson be then? I mean when peterson gets holes 10 feet wide i mean who WOULDNT get mad yards? He breaks to the outside of the blockers and is gone.Same thing with Priest holmes.
