You know what I would like to see added to these statistics?
- Age of player for each data point ( you mean 32 year old Curtis Martin will likely drop off from 31 year old Curtis Martin)?
- Passing ability of each team for each data point (it isn't hard to stop Jamal Lewis when Kyle Boller is the QB, or Stephen Jackson when an old injured Mark Bulger is your passer)
- The offensive line turnover year over year (Not listed, but do you think it's an accident that Shaun Alexander started declining around the time Steve Hutchinson left the team? For that matter their entire offense did)?
- Other considerations (Larry Johnson seems to be the darling example of these stats, but consider that he was part of a terrible 2007 squad that fielded Damon Huard as a QB, he got injured, and they had zero offensive capability. The next season his YPC was actually up but with little opportunity, and he got suspended)
Not many of the RBs on this list match Murray's situation. The RBs were either older, were part of otherwise putrid or declining offenses with OL turnover or had personal issues. The ONLY thing you can point at Murray and say that he would be liable to repeat is the injury portion. He is young, part of a very strong offense overall with a great QB and WR corps, and very little OL turnover. I love statistics as much as anyone in the world, but I really feel like a lot of information is ignored when I see this put up.
