Watching the first half of the UNC game tonight because you figured it would get away from NC Central and indeed the score is 72-30 right now with 8:00 left in the second half.

I just like this sequence from UNC because I think that if you play a half-court M2M pressure, much like the way Duke plays their M2M, the assumption is that you will give up backdoor layups. Yes, the chances are higher, but that doesn't mean you can't teach and drill your players to counter those tendencies. With good footwork and active hands, a good defender can still put a ton of pressure on the wing pass AND still recover against the backdoor as shown in the following video clip:

In the picture, you can clearly see that Justin Watts has both hands in the air, not on his hips. With great lateral foot movement, he's able to adjust to the backdoor cut.

Also notice that he doesn't attempt to turn and face the ball, instead he just focuses on getting back on his man with his arms up and hands in the passing lane, and getting the steal. I see a lot of young players in that situation pivot towards the ball, back facing their check, then try to make the play when their check is already at the rim.

And the Tar Heels finish it in typical fashion, on the fast break.

For more info on the Carolina M2M defensive system, check out Roy Williams' DVD on The Carolina Defensive Numbering System & Drills. With so many new faces, its hard to imagine the Tar Heels repeating as champions, but if Coach Roy Williams is able to groom the younguns he has on this team, they could do some real damage in 1 or 2 years.
