I'm not surprised Oubre only got 1 game, it's the playoffs, they'll suspend you if you go way overboard but the suspension is always on the light side. I bet if this was the regular season he gets 2 games, one for charging at Olynyk and one for making contact with an official.
I'm still waiting for the suspension of Morris for throwing Horford into the stands after the play was over.
I didn't really find that to be suspension worthy. It wasn't a shove the back, and Morris didn't blind side Horford. Two guys went after the ball, and one guy knocked the other to the ground, that is a common foul to me. A hard foul, yes, but not anything outrageous.
