I built something simliar to this back in 2009 for college football coaches. I was planning on adding more for other sports as well as for players but there weren't too many using twitter back then: http://web.archive.org/web/20100325212936/http://www.coachtw...

Seems like everyone is tweeting these days and this is a much slicker interface than the one I built. Good job!

Totally, what's the next sport you'd want to see?

I've added a few soccer teams already you can check out at http://tweetsfc.com/soccer
