BB trying something unorthodox on D in a key game can almost be expected.
Remember putting Rodney Harrison at cornerback (covering Marvin Harrison), not safety, and playing Ty Law at safety, not corner, vs. the Colts?
The Colts were dumbfounded. Marvin Harrison was blasted over and over and made one catch for 6 yards in the first half and finished with only 3 catches for 19 yards. Law had three interceptions. Rodney Harrison had a game-high 10 tackles, an interception and forced a fumble on Marvin Harrison.
The mystifying thing, of course, is that when your unorthodox strategy in not working, why won't you change it?
I'd guess that we won't know that, ever.
