I think these comparisons are more difficult to make these days. For example if you look at hockey, the game has significantly changed since the 80's and 90's. Comparisons have been made between guys like Crosby and Gretzky. The question is, if Gretzky played today, would he have broke all those records? Maybe, maybe not. The dynamics of most team sports change over time, as do the types of players, rules, etc... so I think it would be difficult to say. Maybe if Kobe played at the same time as Jordan things would be different? All good questions.
