One hasn't been mentioned yet and really doesn't quallify, statisticly speaking, but may still make the HOF before it's all over.
I thought I would give you a few facts and see if you can guess who it is. (No Googling, Please).
He started at QB for the Denver Broncos in his rookie season. He set the Bronco's record for TD passes by a rookie (14). His 17.1 yds per completion that year still ranks 18th all-time.
He has 2 Super Bowl rings and was selected to the Pro-Bowl once.
His career spanned 8 years with 7 different teams.
