Harbaugh was playing Dr. Frankenstein. He created the monster but couldn't control it. At least Dr. F stayed to try and protect his monster. Harbaugh, the whiner that he is, just packed up and ran.

If he can still play football, then he ain't done. I heard Bomani Jones this evening talking about the specific incident, and what little we actually know about the circumstances. He even compared Smith to Gallette, saying Junior's situation/character issues were a lot worse (referring to the video of him whipping a woman with a belt).

I seem to recall Smith turning things around after Mike Singletary was fired. Sometimes the right/wrong environment means everything. So, you never know...
