The scouting report for the knicks defense is that they don't defend the 3, or sink so far into the paint that it's almost impossible to recover.
They go under screens almost every time in order to protect the drive/paint, they never trap, have low IQ defenders, and the communication comes every 8 plays.
I understand Rambis Philospohy, and it's not a bad one if you had the talent. Melo does not communicate on defense at all, he rushes to help someone and leaves his man wide open. Rose, Lee and Holiday, they are going under the screen 8 out of 10 times (fear of contact).
IMO once you go under the screen your in trouble if the ball handler doesn't penetrate, jennings tries more than anyone on the team, but he's not strong or quick enough, and his man penetrates enough to suck in in the defense and 3 guy become wide open for a 3.
Like i said in the game thread, the knicks prepare for game like they look at a stat sheet.If it's a low% 3 point team, there's no emphasis on perimeter defense, if't the other way around, then it becomes lay-up-city. The coaching staff has to take ownership as well as the players.
One of the reason woodson/mda was like switch on everything was because it's easier that way, but that also requires players who can guard multiple position.
Another thing is the unfamiliarity when you open up your rotation, thats where communication comes in. These guys have not played together long enough to know what your teammates likely going to do, or capable of doing, thats why the blank stairs come after they give up another wide open 3.
