Calvin Abueva plays rough defense, no different (or to a lesser degree) from many other players e.g. Pingris, Ibanes, Arana, R,Reyes, etc.
As for the flopping and perceived dirty play, I've seen much, much worse from Tubid - who is probably the dirtiest one in the current generation, even when he first came in the league.
As for the other antics e.g. smiling, gestures, tongue wagging, etc ...... many others do this as well.
IMO the reason why many opposing players get irritated by Abueva is because he is legit ...... he is very and uniquely talented.
He doesn't back down despite being a rookie - which is the right attitude all rookies should have.
James Yap & Pingris should cool it ....... Yap has long been the most protected player in the league - the refs calls mostly goes his way and he's crying over someone who plays no different from any of his usual guards e.g. Ibanes, Arana, Tubid, etc.
