Embiid is a real punk. He flopped, pretending to get an elbow from Drummond causing Drummond to get ejected with his 2nd tech.
The NBA really needs to come down on flopping. Especially the egregious incidents. I think suspensions are the only way to fix it.
They should hand out technicals after the fact. I know it won't hurt them in the moment but that could lead to suspensions for players down the line for accumulating too many. I think in cases like Drummond getting T'd up for Embiid's flopping should also move the technical to Embiid's total rather than Drummond also. I remember reading that all technicals cost players, it's not a huge amount but it's something like 2500 for each one, which is something else to keep some from flopping. They won't cost their team a point but they will get that technical, lose some cash, and possibly face a suspension if they keep it up. Guys like Draymond Green would need to quit flopping altogether since he typically hits the tech limit already.
