I do think that they need to find some excuse to let Watson play with the first team this preseason game 2 or 3. They need to do their due diligence and make sure he's not the right guy and that he wouldn't look even better with the first team and against a first team defense.
I was surprised too, when I saw the flag I thought for sure it was due to slapping the QB's helmet slightly.
Glad to be wrong in situations like that, so many flags have gone against the Texans and the defensive player actually committed a penalty right before the flag was thrown, I just assumed they were gonna call it.
