They were determined and would not be denied. The Texans insisted on the Colts getting a 21 point lead and by golly they made it happen.
What do you do about this at the half? What can you possibly say to these guys to make this seem like it's going to suddenly get on track? The defense has given up 21 points, the offense has been the worst I've seen this year and specifically the offensive line looks like it doesn't belong in the NFL and they look like that against the COLTS! Carr has to be starting to question what they're doing at this point I think.
When things should be starting to come together they look like they're falling apart. If the Texans stumble through the rest of the season looking like they have the last couple of weeks then I would not be completely against another look at what they've done to the run blocking scheme. It's completely not working with this group of players and with this back. With no running game (or even a threat of a running game) the Texans are their 2002 selves with marginally better pass protection.
Fitz makes bad decisions. That's not going to change.
