How can it not be? Starr is the only Quarterback in the history of the game to win five championships and was at his best when the pressure is what at its tightest. His 9-1 Playoff Record and 104.8 Quarterback Rating tells you that. While Favre would obliterate his statistics, Starr put up great numbers for Quarterbacks of his era retiring with the highest completion record in the NFL.
Oh, and is not “Bart Starr” the greatest name for a Quarterback ever?
Throw that name on any QB today and they would probably see their QB Rating rise by five percent just through osmosis.
