This list is omitting some of the greatest players of all time. Marino, Elway, Namath, Earl Campbell, Bradshaw won 4 Superbowls. Mean Joe Green and the list goes on.....
Interesting quiz, though impossible to select a 20 best. Leave in Manning or Elway, leave in Sanders take out Smith and Jim Thorpe, and so on. Single best cornerback, tight end, center and offensive guard of all time, whoever they are, don't make the list.
This quiz is missing some big players like Ryan Leaf, Jamarcus Russell, Reggie Bush, Darren McFadden, Alexander Hamilton, Dwayne Johnson, Vince McMahon, Alexander Graham Bell, Benjamin Franklin, Obama bin Laden, JJettas, Augustus Caesar, Talking Ben, Chris and Martin from Wild Kratts, and so much more.
Wow, this was harder than it could have been. We are given only the players position. I did score 11/20, but I expected better. Oh well, thanks for the quiz.
