I'm sure back in the day Brook Lopez and Robin Lopez would put down their comic books at the same time and already know that the other one wanted to go play basketball in the driveway. They'd go out there and battle one-on-one, wondering if some day they would be able to play against each other in the NBA.
That's the kind of connection twins apparently have. There is an ESP type of deal that lets the other one know or feel the same thing at the same time.
When Brooklyn Nets big man Brook drove down the lane against his New Orleans Hornets counterpart, he didn't show any brotherly love toward Robin. He rose up, shieled his body with his off-arm, and threw down a big dunk against his brother.
I'm not quite sure how twins and their telepathic powers work, but I wonder if Robin felt embarrassment for getting dunked on, did Brook embarrass himself as well in the process?
