Let me spice things up a little bit.
Overrated:- Vince Carter
He was at this best when playing at a fast pace. Great player for the regular season, not so much for the playoffs. To put it another way, imo he was an entertainer, not a winner.
- Harden
The same as above, plus he plays no D whatsoever.
- MJ (yep, I said it)
Widely considered to be the undisputed GOAT. I don't believe he's the GOAT, hence imo he's overrated.
- Kobe
Terrible teammate. Most of the times he was only looking for his own shot.
- AI
Same as above. Most of the times he was only looking for his own shot. Unlike Kobe, he was a below average defender as well (to say the least). Yes, he led the league in steals three times. Gambling for steals isn't necessarily indicative of good defense.
- Wade
A bit too much ball dominant for my liking, especially for a guy with a score-first mentality. Imo, he was a one-dimensional scorer. Excellent slasher, below average shooter.
Underrated:- Klyde Drexler
- Manu Ginobili
- Reggie Miller
- Drazen Petrovic
