It was absolutely holding, but they didn't call it. The holding gave Brees the extra second to get rid of the ball
Absolutely the Colts have been better with Hasselbeck this season than they were with Luck at QB. It's just one of those weird things where Luck has a terrible season and Hasselbeck manages to be just good enough.
Wow, that's three missed holding calls against Clowney this half. That last one was just bad. He would have had a sack and possibly a strip to go with it.
