VIDEO: Grayson Allen Ejected From Summer League Game After Taking Cheap Shot Swing at Grant Williams
By Adam Weinrib

Ahhh, some people never grow up! Grayson Allen, with so much room for additions on the maturity scale, proved again on Thursday night that he just doesn't have the patience to become a better person on the court. We're not sure what Grant Williams of the Celtics did to get under his skin in this Summer League contest, but we're sure it wasn't much! Allen did what Allen does; flew off the handle, in plain sight.

Weird he used his arms this time!
Of course, this was shortly after Allen attempted to take down Williams elsewhere, to no avail.

All things considered, it's probably best for everyone that Allen went home early after the swing at the dome: the Celtics get to feel safer on the court, and the crowd gets a chance at one public serenade of Allen, which is pretty much all his NBA (and collegiate!) career is good for.
Grayson Allen just got tossed for picking up his second flagrant. Crowd singing "nah nah nah nah say goodbye."

It's often unpredictable, but in the end it's right. I hope you had the time of your life.
Good riddance, don't come back.
