Alex Boone previously defended Jim Harbaugh, but his comments this week represented a major departure.

“He does a great job of giving you that spark, that initial boom,” Boone said.  “But after a while, you just want to kick his ass. . . .  He just keeps pushing you, and you’re like, ‘Dude, we got over the mountain.  Stop.  Let go.’  He kind of wore out his welcome. . . .

“I think he just pushed guys too far.  He wanted too much, demanded too much, expected too much.  You know, ‘We gotta go out and do this.  We gotta go out and do this.  We gotta go out and do this.’  And you’d be like, ‘This guy might be clinically insane.  He’s crazy.’ . . .  I think that if you’re stuck in your ways enough, eventually people are just going to say, ‘Listen, we just can’t work with this.’”
