Wozzvt has some good info about shotblocking. You should check out some of the blogs he has made on the NT offsite about shot types and defense. I didnt read everything on this forum so i dont know if it had already been mentioned. Also another thing i dont know if its been mentioned, shotblocking also disrupts those "driving" layups and shots. I didnt notice it at first but when Wozzvt mentioned it I started looking for more shotblocking and have noticed a big difference in my team defense. Even a couple guys with 10 SB can really help a team out down low. On those inside shots its a mixture of ID and SB against IS that will be the deciding factor on made shots from anywhere inside whether its a shot or layup or dunk. Like I said Wozzvt was the one that figured this up using a formula( I believe a regression formula).
