In one sense they're right - today's loss wasn't a big deal for the Heels.
The idea that "Roy let them lose" is of course total crap. Every quality team wants to win every time it steps on the floor. And the idea that one more day of rest is a desirable trade for a loss is just as craptastic.
But other than the sting of not winning the ACC Tournament the loss is pretty benign. The Heels are still most likely a #1 seed and the loss doesn't really scream out that they are a team in trouble unless Lawson is unable to play.
