nah. i mean, he is a damn good tennis player, could rack up a lot of majors no doubt...but i think fed's game was just more lethal--absolute crazy good spot server, and better at flattening out the forehand for putaways...for starters. pete had a bigger serve but as a package i don't think there's a player in history with a better serve +1 than roger in his prime...king of the 46 second hold.
carlos has amazing touch and creativity, but not sure how you put him above fed in that department either.
at the end of the day he's his own player and apart from novak, the best all-around player on tour hands down. certain play styles definitely challenge him but there's nobody else on tour i'd point to as sitting above him skillwise or potential-wise (sgain, novak being the exception.)
