On Monday, I posted my Opportunity-Neutral Rankings, i.e., how players would rank if they all had the same number of attempts/carries/targets. Today we'll eliminate a different variable: health. These rankings are assuming every player were 100 percent healthy for every game in which they're eligible (suspensions are still counted against them, however). For these I used PPR:

The beneficiaries are obviously the injury-prone players like Rob Gronkowski, Julio Jones, Arian Foster, Ryan Mathews, Tony Romo and DeMarco Murray. Durable players like Jason Witten, Vernon Davis and Alfred Morris slip down. If you believe injuries are, to a large extent, random, these lists offer an idea of who's undervalued and overvalued based on misperceptions about health. Of course, Darren McFadden, who used to rank highly on these lists, is a reminder not to buy into the "injuries are random" school entirely.
