I'm 28...not sure why that's important but I know that Jerry Rice isn't the best football player of all time...even you questioned that yourself.
I personally value the contribution of Jim Brown over Jerry Rice just because he got 106 TDs on the ground, over 12,000 yards on the ground, 3 time NFL MVP, and a bust at the Lacrosse Hall of Fame In the days where Running Backs are flashes in the pan, Jim Brown is the Iron Man of the NFL.
Sampras is better than Federer because he won eight Wimbledons and 5 US Opens going against stiffer competition (Agassi, Chang, Courier, Becker, Ivanisavic, Henman etc). Should be common knowledge.
Other selections besides Babe Ruth for best baseball player contrary to your belief IS NOT null and void. There are great arguments to be had regarding the careers of Hank Aaron, Barry Bonds, Satchel Paige, Lou Gherig, Ted Williams or Joe Dimaggio. However, based on stats Babe Ruth is the best baseball player ever...there are just things (no black players for instance) that may hinder Ruth's ultimate legacy. At least in my eyes. But I'm a Baseball fan, I love to argue.
Picking on Ali's record is silly, look at the people he beat.
Pele is better than Mardona, but i believe Messi will end up having the better career. Don't need to be over 30 to know that one
I just don't like the fact that you think you're top 2 head on here. I despise unearned arrogance.
You don't know what your talking about when it comes to Tennis.
First off the competition is just as good if not better. Secondly, Federer already dominated the sport and would be even more dominating had Nadal not stole the show once he got out his prime.
At one point, Federer made the SEMIS on 28 (TWENTY EIGHT!!!) STRAIGHT GRAND SLAM TOURNAMENTS!!!!
That's unheard of. Sampras was GREAT and Agassi was good. Federer and Nadal > Sampras and Agassi.
