I'm Just Asking

In the discussion of Best Quarterback Ever, why doesn't anyone mention Bart Starr, who won 5 NFL championships plus 2 Super Bowls in Green Bay?

In his era, Starr was the one calling the plays on the field, not just executing whatever was chosen by Vince Lombardi and other coaches. He (and Johnny Unitas and other legends of the time) defined the term "field general," yet he's given short shrift in modern conversations that are limited to Tom Brady and Peyton Manning.
