Since the Jacksonville Jaguars announced that Travis Hunter underwent season-ending surgery due to a non-contact knee injury in practice, there's been chatter that they should stick him to one position once he comes back. The discourse centers around the fact that playing two ways was too much for the reigning Heisman Trophy winner to bear.
That said, that argument falls under the slightest scrutiny. For starters, Hunter was an ironman at Colorado, and never did playing two ways become an issue. A counterpoint is that the NFL is more intense, and that's true, but NFL players get hurt all the time.
