Could be. I'd be concerned if I was a Texans fan, though, that his instinct was to tuck it and run as soon as the play broke down.
Of course. This play calling isn't helping him any and could hurt his long term viability. They need to set him up to succeed. I think part of that will be telling him to stop running. It's a big part of his game, but they need to get him used to hanging in there. Once he learns that then he can get back to running to buy time.
