Spot Throw-in Question

[hhktwins]

I saw the play and thought the player was within the 3 foot box, even though the announcers applauded the call, and Sendek didn't say boo. It's amazing how many people think that you can travel on that play. In fact, the official used the traveling signal to indicate the violation. I thought it was a crucial mistake, although NC State still had their chances after that.
