Anyone good with Ratings want to help me rate these two guys

Im trying to do ratings for Yao Ming(Before the Foot injuries) and T-Mac(Magic Years) But idk exactly how to rate them.
Also would like sigs skills you would give them?

For instance I gave Yao Eraser, Scrapper, and Post Proficiency and T-Mac has Posterizer, Dead Eye, Highlight Film, Microwave, and Closer.

Any help is appreciated. Thanks

Yao = 91
Eraser, Scrapper, Post Proficiency, Spot Up Shooter, Bruiser (he was really tought to guard because he weighed a lot and was really tall, you had to give all your energy just to guard him)
T Mac = 94 (Magic Years, specifically 03)
Shot Creator, Microwave, Closer, Deadeye, Interceptor (he got great D back then)

T Mac might even be more than a 94 his stats were amazing
32 PPG
6.5 RPG
5 APG
1.7 SPG
2.8 TOPG
45% FG, 39% 3PT

Compared to like, when D-Wade was a 97 in 2K10 or 2K9

I wouldn't give Yao eraser. I reserve that for players that can make athletic blocks at the rim. He will have a solid enough block rating to get blocked shots without the skill. Also, I don't know about him having scrapper either. Post Pro, cool.

Spot up Shooter for Yao? Really? Why?

He's like Bosh or Gasol you give him an open baseline jumper and it's automatic. But yeah about Eraser, he kind of doesn't send the ball to the crowd like that so..

Yea but that can be achieved without giving him Spot Up. When I think of spot up I think of long distance shooters that make a living off of the shot. Korver comes to mind. JJ Redick comes to mind. Not big men.
