Did Grayson Allen intentionally trip a Louisville player?

That looks pretty dirty to me.

The game between Duke and No. 13 Louisville was a pretty close one with the Blue Devils prevailing at home. It looks like there was home cooking on defense too as Grayson Allen seemed to have blatantly tripped Cardinals forward Raymond Spalding.

I might be a little frustrated too if I had dropped out of the rankings for the first time since 2007. But there's just no room for tripping another player to stop a play. That's not a basketball play.
