Mendenhall is a good buy low right now, but only because he can be had for next to nothing. Anyone who would prefer Mendenhall to Mcfadden right now is either insane, or just saying that to save face. Anyway, i am not about to get into a three page thread about it again. We are through more than 1/3 of the season, and so far it is pretty safe to say that Mcfadden, Chris Johnson, and Matt Forte are better than Mendenhall, Ray Rice and Tashard Choice. EBF, sometimes its OK to admit that you are wrong.
I don't think there's any strong evidence to suggest McFadden > Mendenhall. I would still take Rashard over DMC in dynasty leagues. I definitely think Forte > Choice and Johnson > Rice as of right now. However, it's important to note that only two of those guys are competing with Pro Bowl type RBs for touches. One of the main lessons this RB class is teaching me is the importance of opportunity. Almost without exception, the rookie RBs who are having the best seasons are the guys who had the weakest competition for touches (Forte, CJ, Slaton). That's not such a big shocker. You can't produce when you aren't getting carries. On the flipside, almost any stiff in the NFL can produce decent results if you feed him the ball 15-20 times. Look at what Correll Buckhalter and Mewelde Moore did recently. If they were rookies people would probably be touting them as the next star RBs. You have to have some perspective. It's important to remember that you shouldn't use short term results to judge long term rankings. Every FF player on the planet would've traded Reggie Wayne, Chad Johnson, or Santana Moss for Anthony Thomas after their rookie seasons. I vividly recall the days when it was fashionable to call Larry Johnson and Aaron Rodgers draft busts. My point here is that you have to give guys time to develop. What we think of these rookies is different than what we thought of them 6 months ago. What we think of them 6 years from now will be different from what we think of them today. So coming here and saying, "You were wrong about Mendenhall" is just silly this early in the game. Mendenhall looks about how I thought he'd look and I think he'll be a solid starter when he gets his opportunity 1-2 years from now. As for McFadden, I never really felt his game fit the mold of an elite FF back. He showed some flashes in that KC game, but has otherwise looked ordinary. That includes the preseason when he was 100% healthy. Add in the fact that he's stuck on a rudderless Oakland Raiders organization and there's certainly some cause for concern. He's still ranked pretty high and there are still people who think he's a star in waiting, so I think it makes a lot of sense to move him.
