Some clowns on the gameday thread were saying he was stupid and reckless.... but if he had slid down to avoid the hit, and come up short of the marker, the same clowns would have been crying about him being a "coward" and "afraid".
The QB has to protect themselves. No first down is worth what happened to him on that play or a play like when Jameis tore his ACL a couple years ago. I get the competitiveness, but they have to be smarter than that. Live to play another down/game.
