BS penalty. Int. grounding on Jameis.

Why? THE CLOCK WAS STOPPED. You didn't need to run a kill the clock play. This was a bit of a blunder by DA and the OC. And Winston as well.
As has already been noted. It seems that JW, Carmichael, and Allen all thought the clock was going to start, since the officials were running full speed to set the ball and move move the chains, like Landry was inbounds.
