I enjoy watching sports, as much as that surprises people. But I'm not big on following any particular person or team. here are some that I know or like for one reason or another. I'm certainly no expert on this.

Football - Coach Jon Gruden (didn't they win this year? A friend of mine has a crush on him.)
Soccer - ?
Baseball - Tug McGraw
Basketball - Coach Bob Knight (I am forever a Bobby fan - FOREVER), Michael Jordan (because he's a great guy and so talented, was not so talented in high school and that's so inspiring)
Boxing - ?
Snooker - ?
Pool - ?
Billiards - ?
Tennis - Pete Sampras, Venus & Serena
Golf - Tiger Woods
Formula 1 - ?
Rallying - ?
Athletics - ?

Okay, so a lot of that is left blank!
