I don't know what your criteria is for Wade's best seasons shytting on Iverson's best seasons. Iverson averaged more pts, more assists, shot better 3pt %, got to the line more and shot a better FT % for his career. Like I said it's up for debate, but Iverson's best seasons are better than Wade's best season and that's actually not up for debate.
Wade's best season
30.2 PPG (49% shooting) / 7.5 AST (3.4 TOV) / 5 REB and he did that playing 38 minutes a game
The only season where AI had more assists (7.9 AST), he was also much less efficient (30.7 PPG on 42% shooting) and 4.6 TOV.
So AI averaged a couple more points on way less efficieny, had way more turnovers, and wasn't as good defensively.
Pick the season that was better than Wade's best.
