It's a moot point because the midget isn't coming back, but when he came here in 1998 he wanted #2 (his previous NFL number) and Steve Christie already had it, so he asked for #11 (1+1=2, and 11 is half of 22 which was his college number, which can't be issued to QBs in the NFL). They gave him #11 and then traded for RJ, who asked for #11 (his Jax and USC number). Since RJ was slated to be the starter and Flutie hadn't taken a snap in Buffalo yet, they gave RJ #11 and told the midget to pick another number. The midget took #7, presumably because it sort of looked like a 2.
If the midget came back, which he won't, he would probably take #2 since it's available now.
