Although I think I said I wanted Howard McHale'd yesterday, the more I think about it, the best get back is just to send Howard home for the summer. Stay above the fray, play hard, play relatively clean (ie, keep the elbow's down below the shoulders), close out, box out, don't let nelson get comfortable by switching multiple defenders on him and closing the lane, and most essentially, WIN THE GAME.
And if the C's want to make a statement, I'd said Rondo or Pierce right at Howard in an early possession with the intention of dunking on him at all cost. Even if he clocks one of them, it sends the message that we're attacking the rim hard, and without abandon. Plus, another Howard hard foul would fire up the Gahden.
