No, Mr. Cavaliers Fan With Courtside Seats, I don't think it's useful for you to wander onto the court and approach Kyrie Irving in the middle of an Andrew Bynum post-up in order to show him your "Kyrie Don't Leave" t-shirt. In fact, it might be counterproductive.
This comes a year after a similarly well-meaning but clueless Clevelander went onto the court wearing a shirt that expressed to LeBron James how much he missed the star. It seems like after that troubling flub security at The Q might have been tightened up. Apparently not.
