Corey Kiner is your Patriots third running back, and it's not even close anymore. With Terrell Jennings sidelined, the depth chart battle came down to Hassan Haskins, Lan Larison, Jam Miller, and JaMycal Hasty—and Kiner separated himself enough that Mike Vrabel and Eliot Wolf felt comfortable making the call before cutdown day. That matters because it tells you something about what this coaching staff values in a reserve back: whoever earned this role did it in practice reps that counted.
The setup here is straightforward. Rhamondre Stevenson and TreVeyon Henderson are your guys. They're the workhorses. Everything below that is organizational depth, and organizations that win don't sleepwalk through the third RB competition. Kiner beat out legitimate camp bodies—Haskins, a guy who's been in the system, Larison, Miller, and Hasty all had legitimate paths to this role. The fact that none of them stuck suggests Kiner either ran hard, stayed healthy, or did the little things (pass protection, special teams positioning, communication) that differentiate players in August.
This is what happens when you have a new regime under Vrabel. These decisions get made on merit during camp, not on name recognition or past draft capital. Jennings' injury opened the door, and Kiner walked through it. Whether he was a camp invite or an undrafted tryout, he earned his spot in the three-deep rotation heading into the regular season. That's the baseline: prove it when it matters, and you get the job.
The broader picture is less flashy but no less important. Your backup running back room behind Henderson and Stevenson needed to be sorted, and now it is. One less thing for Vrabel to manage as we get closer to Week 1. The staff knows who's in the car and who's riding the bench. That clarity—that decisiveness—is what you want to see from a new regime in Year 1.
