re: Other Hall of Fame QB's pay tribute to Peyton F. Manning

"he changed the way the position was played".

I really don't get this. Yes, he is one of the best to have ever played the position, but how did he change the way other QBs play the position? Because he became a master of film study and was able to read defenses and audible to a new play? That was done for decades, most of the QBs from the 70s & earlier called a lot of their own plays.
