In case you missed it last night, here is great quality video of the last two plays of the game from The Basketball Jones. It hurts to watch, but you can be sure Collins is making the kids watch it again and again. That's how you get better.
The biggest problem I have with this play isn't the switch by Thad and Jrue, it's the fact that there is no one guarding the basket. Sure, the Celtics spacing is always amazing, but with 6 seconds in the game, someone has to be close to the basket. If you watch, no Sixer has both feet in the blue part of the paint until Lou leaves Nate Robinson as Garnett puts it in. Having a capable big man defender would help, but a lot of this is on Collins.
