Well, FWIW, there was that 1 game which I consider the greatest feat of a rookie, or maybe any player, and that player is of course Magic Johnson. I've mentioned this many times in this thread because I could only dust off my not-so-good Lakers' sentiments a few decades after the 3 Finals we've been through in the 80s.
Kareem went down with a sprained ankle in Game 5 vs the Sixers. He was averaging around 30 points for those 5 games as was the leading scorer for the entire series. Magic was tasked to play his position and he ended up with 42 points and 15 rebounds and some assists to blow out the Sixers and capture the title, on his rookie year. I don't think he ever scored 42 points after than in his career.
And prior to that, he just lead his college team to the NCAA title.
