BQ said (I paraphrase) that the Steelers defense has a hole - that they tend to leave the middle of the field open and that could be exploited. Should have shared that with the rest of the Browns, as they did not do so hot last time they played Pittsburgh. Some of the best QBs in the game this year have played against the Steelers and not had a good day. In his defense the middle is a known hole in the Cover 2 and that's why they sometimes plat a Tampa 2. But I think it was a weird thing to say.
Looks like Quinn was right...the middle was open all game!
