HOUSTON -- The signs started popping up everywhere. J.J. Watt was starting to look like his old self.
Derek Watt saw it while he was working out with his brother in Waukesha, Wisconsin, during the offseason.
Johnathan Joseph saw it when he was at the Houston Texans' practice facility in the middle of the summer and watched Watt running half-gassers -- a sprinting drill -- in less than 14 seconds.
