Oh c'mon, who would want an Ahnold, over a Karelin in their primes. Karelin is a natural. Even Ahnold admits he was a skimpy dork before he started working it.
If Karelin had grown up an American, he never would have had the career he did. He would have been gobbled up into football. I do think he would have been the best defensive end or inside linebacker we've ever saw, if he had played the game.
Ahnold couldn't succeeded in either sport.
