Isaiah Thomas is a shot blocker now. The Celtics 5'9" guard swatted a layup attempt by Demarcus Cousins.
Cousins is a 6'11" center and might want to reconsider his career choice. To be fair it does appear that he lost the handle on the ball before Thomas sent it flying off the backboard.
That didn't stop Thomas from screaming, "get that shit outta here." And if you're 5'9" and you just swatted a 6'11" guys shot, even if he lost the handle, you're yelling about it too.
