Jeffler
See You At Game 3
I know he started as 9, changed to 99, and had to wear 20 for one game, but are there any other occurrences?
Maybe in some press photos (you can see him in a number 20 Indianapolis jersey too) but if I'm not mistaken he wore 99 in all 8 games for the Racers, here is his first professional goal (as a Racer obviously) and he has 99 on.
