This is it in a nutshell.Meh, I dunno. Celtics fans have a long standing history of cheering loudly for a deep bench player regardless of said freakiness. There was nothing freaky about Terry Duerod or Conner Henry in the 80's, or Scalabrine, or the fans fondness for the Sichting's and Walter's of the team. Whenever there is a "fun" team wearing green the Celtics fans have historically selected a guy that they want to see on the floor at the end of blowouts regardless of freakishness level. Aside from the obvious height, Fall has the charisma to attract a cult following.
Personally, I've typically been a "root for the underdog" fan in terms of favorite players. In many cases the rookies or utility guys are the defacto underdog. Leon Poe was a personal favorite because he was always fighting through knees that were grating like tectonic plates. The guy at the end of the bench doing extra reps, more conditioning, fighting to get on the field of play - that's my guy. I put Tacko in that group - because he is so raw at his profession - AND, he seems to have the same perpetual smile that Kemba has. Let me see that you are human, let me see that you are busting your butt, let me see that you recognize the opportunity in front of you and are grateful for it, be reasonably likable, and I'm a fan. It's really a simple formula. I've never been a fan of the brooding athlete type. If you don't like the limelight, choose another profession.
I like me some Tacko fall, I'll root for him in any uniform.
