Minnesota Player Defensive Ratings

I have a college basketball game that I update each year with all the Big Ten players. Most of the game is statistically based, but I also need subjective defensive rankings for each player.

Note that you should not consider shot blocking or steals, as those are already included.

Rather, defensive rating should be reflective of a player's ability to prevent his player from getting the ball and/or his ability to make shot-making difficult.

So, rank the following Gophers in order from best to worst defender:

Westbrook
Johnson
Nolen
Hoffarber
Sampson
Iverson
Carter
Joseph
Busch
Abu-Shamala
Bostick
Williams
