No way. Agassi was more talented than Pete, he just was a mental midget against him. Nobody ever mentions Pete as having an enormous amount of natural talent, even Pete wrote in his book, "I never was the most talented player, but I approached the game with a hard work ethic and the desire to constantly improve. Both of those things served me well."
Pete worked hard, was a mental giant and had a monstrous serve. Andre was by far the more talented of the two. I watched them both as juniors and nobody thought Pete was going to do a damn thing when he was 13-15. Whereas everyone knew Andre was going to be an enormous star by the time he as 13.
