Out of position, like always. The dude is garbage as a free safety. Either way though, Carroll should never be on Andre Johnson. Ever.
That could have been Revis, and if you go one on one with AJ, AJ is gonna win that battle more often than not. There should have been safety help and I think there was supposed to be safety help. If Smith is focusing more on Daniels, Davis is out and Will Allen is in the slot . . . you gotta put Nolan Carroll on the boundary. He didn't have horrible coverage, he needed safety help . . . where it was, who knows.
