Wes Welker refuses to pick between his quarterback friends

Denver Broncos wide receiver Wes Welker has admitted that he simply cannot choose who the better quarterback is between his friends Peyton Manning and Tom Brady.

Welker's Broncos take on his former side the New England Patriots on Sunday, with the winners progressing to the Super Bowl on February 2.

On Wednesday, he told reporters: "It's like comparing Picasso and Michelangelo. It's so hard to compare the two. I honestly couldn't even tell you. Both men are great quarterbacks and great guys."

Welker, who has played for both teams with both quarterbacks, has caught 10 touchdown passes from Manning so far this season.
