Nothing??
So improving them by 10W with a weak ass team, is nothing?
Having one of the best peaks/seasons in 1977, just playing like an absolute beast, taking them to 53W with a weak ass team, with a new and young coach in West (who only coached for 3 seasons), tearing shit up in the playoffs (losing to a much more stacked team)... is nothing?
1977-78 and 1978-79 also two pretty great seasons, especially with chemistry-killer, absolutely-no-defense-playing, not yet in his prime, Adrian Dantley, and only Wilkes was a good defensive player pretty much.
And from 1975-76 til 1978-79 ain't close to a decade.
Furthermore, Magic was only clear-cut better than Kareem around 1986 or 1987, and we're talking about a 39 year old Jabbar, mind you.
Kareem had a crazy season in 1980 with MVP, leading the way to a ring, that FMVP is his. He still had some great years after that as a leader/captain/best-player, he had one of the GOAT individual Finals series in 1985 at age 38 against the Celtics with an injured Bird, had it not been for him (you can also say injure to Bird) and they don't win.
So yea you could say Magic was really lucky to arrive at a team a top3 all-time player still in his prime(past his peak) to lead them and take the pressure off, plus Nixon one of the greatest PGs in the league at the time to learn from, Wilkes was a really good player, and Coop started playing the same time as Magic.
