Warren Moon does deserve to be in.
It's the PRO FOOTBALL HOF, not the NFL HOF, so the CFL counts.
* third-highest career total passing yards in NFL history
* fifth-highest career TD passes in NFL history
* fourth-highest career total NFL 3,000-yards passing seasons, with 9
* had ridiculous single game explosions: 7 NFL games with 400-yards passing, and 49 with 300-yards passing, and a 527-yard game against the Chiefs.
* 9 NFL Pro Bowls
* had dominant seasons with 3 different NFL teams: 4690 yards for the 1991 Oilers, 4264 yards for the 1994 Vikes, and 3678 yards for the 1997 Seahawks
* greatest player in CFL history
* 23 years as a pro QB
Hmm.. ok with stats like that maybe I was wrong. I mostly remember Moon as being a big choker at clutch moments.
