I don't think your crazy, but maybe a bit confused.
I think you may have attended either the AFL All-Star game on Jan 21st, 1968 at the Gator Bowl in Jacksonville, FL where Joe Namath (Jets) led the East against Daryl Lamonica (Oakland) of the West in the first half, and Namath and the East battled Len Dawson (Chiefs) in the second half...
OR
The AFL All-Star game played on Jan 19, 1969 at the Gator Bowl in Jacksonville, FL where Joe Namath led the East against John Hadl (Chargers) of the West in the first half, and Bob Griese (Miami) led the East against Len Dawson in the second half...
The fact that you have so many players and teams mixed and matched in your memory of that day leads me to believe the only answer could be an All-Star game...
