I’ve been curious about YPC leaders over the years, particularly as they’re sorted through increasing numbers of carries. Over the next two days, I will look at the YPC leaders using six different carry minimum thresholds: 100, 120, and 150 today, and 180, 220, and 280 carries tomorrow. These cutoffs weren’t arrived at in an analytically rigorous way, just through instinct and personal judgment. I ran a number of different carry thresholds and simply tried to keep my statistical eyes peeled; in my view, these are at least 6 of the minimums where interesting changes seemed to emerge.
As a general rule, though not an absolute one, I’m in the camp that regards YPC as, at best, a questionable stat when it comes to assessing skill and performance, and at worst a misleading and even bunkum stat, to borrow a term from Chase and the crew over at Intentional Rounding. Don’t get me wrong, I’m not suggesting YPC is useless. In fact in some narrow contexts I think it’s even key. But I think it’s woefully overused and over relied on, and I do regard it with suspicion when it comes to assessing rushing and running back value and effectiveness, particularly in “real-game” situations. I think the same holds for mobile quarterbacks, too.
I decided to look at YPC leaders for the 46 seasons since the merger was completed, 1970-2015. Again, no special reason, just to make things more manageable. This would probably get really interesting if we included all pre-merger seasons, but I didn’t do that here. If anyone does, kudos. At any rate, here are the YPC leaders since 1970, sorted at 6 different carry thresholds. [click to continue…]
