TreVeyon Henderson is banged up, and that's a problem Mike Vrabel can't ignore with the Seahawks looming. The second-year back sat out Thursday's practice with an ankle injury as the Patriots squeezed in a bonus session heading into Week 1. In a league where explosiveness at running back dictates offensive tempo, losing Henderson—even temporarily—forces uncomfortable questions about the depth chart.

Here's the thing: Henderson was supposed to be part of the answer in New England's backfield rebuild. Vrabel and Eliot Wolf invested developmental capital in the kid, and now, days before meaningful football, he's watching from the sideline. The Patriots have bodies at the position—Rhamondre Stevenson, Hassan Haskins, Corey Kiner, and others fill the roster—but there's a difference between healthy depth and depth born from necessity.

The timing is terrible. Seattle's defense won't wait for anyone to get right, and the Patriots need their best weapons operational from snap one. An ankle lingering into Game 1 becomes a distraction nobody wants. You're either all-in or you're managing an injury week-to-week, and neither scenario is ideal when you're trying to establish offensive identity under a new regime.

Thursday's extra practice was supposed to be about refinement before the real thing begins. Instead, it's become a reminder that depth charts are luxuries—availability is the only currency that matters. Henderson needs to show he's ready. If he's not, the Patriots have contingencies, but contingencies rarely feel like solutions when the Seahawks are on the schedule.

The next update will tell us everything. Until then, this is a story worth monitoring.
