1990 is one I wasn't that familiar with. 25 points a game on 66% true shooting, 4th year in a row he lead the league in TSP.
He actually had the most first place votes that year too. It's interesting, he won in 93 for 2 reasons I guess (aside from his play, which was def at a lower level than 90, but still obviously awesome) 1) the team was better (62 wins vs 53 in 90, best record in the league and 2) voter fatigue with MJ i guess? He had won the prior 2 years. Actually throw in 3) the narrative of this being his first year with the Suns and them taking a level up. The funny thing is Magic won in 90, which was his 3rd in 4 years and second in a row!
