"He does a great job of giving you that spark, that initial boom," 49ers offensive lineman
Harbaugh himself didn't deny his tendency to wear on people.
"They just don't want to be around you after a while," he said.
Harbaugh and the 49ers parted ways after his fourth season, the first in which San Francisco failed to reach the playoffs with an 8-8 record, though he was already rumored to be on the hot seat before the regular season began because of his overbearing style.
"I think he just pushed guys too far," Boone said. "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.'"
After his separation from the 49ers, Harbaugh was quickly picked up by his alma mater, the University of Michigan. For now, the two appear to be enjoying the honeymoon period, though it might be brief.
