Jim Harbaugh has a .702 career winning percentage. He's won at least 10 games in half of his seasons as a college coach. He totally rebuilt a dying Stanford program, and reestablished a fading Michigan as a serious threat. Hell, he took Alex Smith (thought to be a total bust) and the 49ers (who hadn't made the playoffs since 2002) to 3 consecutive NFC championship games, and a Super Bowl, and they imploded without him.
The guy can coach, and has proven it time and again, late season-fades not withstanding.
I know it's popular to shit on Jim Harbaugh recently but let's not let facts get in the way of a good narrative.
