NFL Week 15: What We Learned

A Derrick Henry stiff arm sounds even scarier than it looks. Henry is known for turning the stiff arm into a work of art, but he took it up a notch in the Tennessee Titans’ laughable 46-25 victory over the Detroit Lions. On a 7-yard run early in the second quarter, Henry was heading toward the left sideline when Alex Myres, a second-year cornerback, tried to wrap up the much larger running back. Henry thrust his right hand at Myres’s head, producing a thundering slap that sent Myres tumbling to the ground.

It was one of numerous highlights for Henry on Sunday, as he rushed for 147 yards and scored his 15th rushing touchdown of the season. Henry is up to a career-high 1,679 yards rushing, putting him 195 ahead of Minnesota’s Dalvin Cook for the N.F.L. lead. Henry could become the first player with consecutive rushing titles since the Hall of Famer LaDainian Tomlinson did it in 2006 and 2007.
