The Jets were the better team and while momentum etc. can change games dramatically, a good team would have responded to bad calls from refs by coming back harder instead of folding. So basically, the Texans proved they weren't as good a team by responding badly.
That said, there were several bad calls:
1) No blow to the head call when Carr when down. "The ball was already in the air..." What BS is that? Every roughing the passer call comes while the ball is in the air. You aren't allowed to hit a QB in the head. Earlier this year one Texan (Smith or Deloach I believe) was tagged after the ball was in the air for brushing his hand on a QB's head.
2) Block in the back on the kick. His hand touched the 5 on 54's back numbers. Don't know how that can be called on the side. Did it affect the play? Probably not, but a gazillion return penalties are called each year that didn't affect the return. Plus, it is one thing to not call a technically correct penalty that doesn't affect a play and totally another to pick the flag up after the correct call was made.
3) Carr's intentional grounding. Has to be one of the worst calls ever. As the commentators said there are 3+ plays in most games where the QB and WR miscommunicate and no one has ever called that as intentional grounding before.
The Texans had plenty of other problems today contributing to losing this game--they didn't need bad officiating on top of it.
