Two things Tennessee Titans legend Chris Johnson wants you to understand about his NFL career ...
#1 -- He says he's a Hall of Famer FOR SURE.
#2 -- He says he's the fastest player EVER!!!
CJ2K's bold claims all went down Wednesday at the launch party for his supplement company in Nashville ... when he told TMZ Sports straight-up, "I think I'm a Hall of Famer" and "I'm the fastest guy that ever played in the NFL."
There ain't much debate about Johnson's speed ... the guy held the Combine record for YEARS with a 4.24 40-yard dash.
But, as for the HOF debate??? That might not be as clear-cut ... Johnson finished his career with less than 10,000 rushing yards and just 55 TDs -- numbers that haven't always gotten guys in.
