I know that Bowles is the hot coordinator coaching candidate this year, but are we really going to go back to a defensive HC? If you're going the defensive coach route, why not Rex Ryan? His GM has given him absolute [expletive] to work with on offense and they've been pretty competitive every year except this one. The problem with both Rex and Bowles is that they run 3-4 defenses. Just an FYI, Harbaugh (with Vic Fangio as DC, who I imagine would move with Harbaugh) ran a 3-4 at Stanford and runs a 3-4 now. I wasn't a proponent of Harbaugh for coach, but that's good to know. That said, like everyone else has pointed out, we don't have some great defense that we need to preserve continuity with.
