Yep, blame the couches, who just brought this idiot back into camp to try again. In his defense, he is also talking about the Adderall culprits and such. Carroll only had about 4 seasons before he becomes another team mascot or an intercom that players stop listening to while speaking, basically a caricature. That's what happened the last time he couched, and it could be happening again, already.
Have to wait and see, but rah-rah coaches like him, make quick impacts and peter out in short order.
