You got a good list, but I'd pick Winslow over Caspar, Butkus over Singletary (admittedly a tough call,) Lem Barny over Lester Hayes, John Hannah over Larry Allen,Otto over Webster (another close call), Michael Strahan over Reggie White, Buck Buchanon over Bob Lilly, but otherwise you're showing a rudimentary understanding of the NFL.
I will teach you, I will make you understand. I will make you a fan.
