Adrian Peterson turned 30 last March. He missed a year of football, had 2,147 carries on his legs and needed surgery to repair injuries three consecutive offseasons.
Plenty of reasons existed to suggest Peterson might not return to his former self this season.
Consider me more curious than skeptical. An MVP season offered as a rebuttal to ACL surgery taught a valuable lesson about underestimating Peterson on the field.
Any concerns about a deterioration of his physical ability have vanished now that Peterson leads the NFL in rushing and looks 25 again.
For proof, watch him execute a signature move: his jump cut.
You've seen it. The way he charges toward the line, comes to a stop if the hole isn't open and then explodes laterally to bounce his run outside.
He looks like he might jump out of his cleats trying to avoid a mass of bodies, or to freeze a linebacker. His jump cut is as astounding now as it was early in his career.
He hasn't lost that step.
