I know this thread was made as a vehicle for the Ted Wells joke, but on a serious note I chose Jerry Rice. Of those options, that's the only one where the style of the game is trending towards it being broken. It's a passing game so if the right talent came along he'll have every opportunity to rack up numbers.
In MLB, with pitch counts and going every five days without exception, pitchers only make about 30 starts per season. They'd have to win EVERY one for SEVENTEEN YEARS and they'd still fall one short.
Basketball is a possibility, but when Chamberlain and Russell and them were playing, I think they were simply overpowering for most other teams. Nowadays though there is a significant talent gap between the real superstars and the dregs, if a player was going off and approaching, say, 70 or 80 points, teams have the talent to at least double team them and force the ball elsewhere.
And hockey, good lord... Wayne Gretzky had 100 assists in a season eleven times. Only two other players have ever had that many in one season (Lemieux and Orr) and they each did it ONCE. Nowadays, with the defensive systems, size of goalie pads, and size of players, the leading scorer in the league didn't even crack 90 POINTS this year. That record isn't going anywhere.
