Dan Reeves it is. Unfortunately I'm old enough to have seen him play for the Cowboys. In the years of the first 2 Super Bowls, Geen Bay beat Dallas in 2 classic NFL championship games, before going on to beat the AFL teams KC and Oakland in the SB. Dan Reeves was a halfback (running back) and his specialty was throwing a halfback option pass. In one of those games with the Packers, he threw one for a touchdown, if I remember right.
I bet I'm the only one on this forum who's seen every Super Bowl.
