I like having haters. It means that the 49ers are a feared team agin. It feels good.
Harbaugh just doesn't give two s**ts about what "perception is around the league" and whether people are laughing at him or not. He just doesn't care.
I busted up laughing at this quote on NFL.com about him: it said "We're sure this idea doesn't sit well with Harbaugh, who doesn't seem like the type of guy who would appreciate people poking fun at him behind his back." This just shows how little the media actually understands Harbaugh. He has one goal and one goal only: winning and he will do whatever it takes to put his team in the best position to win. If it means looking like a fool to the rest of the league, so be it.
And I LOVE that about our coach. None of the best coaches in the NFL give any f**ks to how others perceive them.
