I kind of see the same thing,driving past the defenders is difficult but when I "force" it sometimes I'm able to do it successfully,weird..
For shooting sliders,I used Greenegt tweaks and have pretty good results.
MK,raising the HUM Def Reb to 15 (and lower CPU Attempt Putback to 90) gave me great results in terms of rebounding in my last Raptors @ Hawks attempt.
The blocking tweak is also well done,I thought it might be too much when I blocked 5 or 6 shots in few minutes but I finally got 10 in that match.
Only thing that still bothers me,it's the CPU steals number,well more that "I have eyes in the back and can swat balls without looking" thing,this drives me crazy!
