Ok, let's not overrate Stiemsma here. He was a mediocre post defender as evidenced by thefact that he was practically incapable of defending anybody without borderline fouling out of the game.
The guy blocked a lot of shots and he was usable offensively, but his defense outside of shotblocking was nothing special at all.
As for the above ratings, you rate Terry a 2 and JJJ a 3??? JaJuan Johnson was a horrendous defender!
Also a 5 for Lee? Pietrus was so much better defensively last than Lee is this year. People are overeating Lee's defense based on his athleticism and reputation, but i have not once seen him lockdown a player on defense the way Pietrus sis on a regular basis. I can justify a 4 for Lee, and Pietrus should be a 5 based on this scale, Stiensma a 4.
Dooling, Marquis and Pavlovic were all solid defensively - a 4 for each is about right.
Collins should be a 3 at best. Again people overeating him based on reputation but seemingly have not watched him play. He has defended horribly when he's been on the court and his statistics prove it - he's been our worst defender by a mile. Hollins was a MASSIVE improvement over Collins defensively.
Statistically Terry is our second beat defensive player after KG. This is based purely on stats, so take from that what you will!
Our key difference last year us we had two perimeter defenders who were either elite or borderline elite - Pietrus and Bradley. Those two guys were often on the floor together, and when they were (along with KG) our defense was exceptional.
This season we have one elite perimeter defender and he hasn't played a single game yet. We desperately need a Pietrus type on the perimeter - a strong, long, athletic defensive/hustle minded player. Lee is athletic but he's not big or strong enough to challenge bigger guys like LeBron / Carmello, whereas Pietrus, Daniela and Pavlovic were all capable of defending 3 positions. The ability to throw a mass of defenders at theae guys helped us overachieve as a team.
