I will show PP respect if and when I think he deserves it. If he is going to act like a fool following Horford to his bench then he doesn't. They just got their tails handed to them and he is more worried about his personal ego than the team. THAT is not worthy of respect either.
At first glance of what happened I was ready to consider your overly sanctimonious point that PP overreacted, but after seeing a direct replay of what Horford did, I changed my mind. A little talking on the court is one thing, most players do it, but Horford went way past showing him up. Jabbing a finger in his face repeatedly and yelling at him (on national TV, no less). There is a bit of an unwritten code in the league, in most pro sports for that matter...and rooks like Horford should probably show vets (All-Star vets, btw) like Pierce a LOT more respect than that. I think he forgot the Hawks are still down 2-1.
Truth has hit several game winners/big shots in his career and I can't recall him physically showing up a player to their face on national TV. As for your comments about Paul's ego coming over the team, I would be more worried if one of the C's had no response to an insult like that. I have no problem with Paul getting upset because Horford was way out of line, no doubt.
He should be thankful it was Pierce and not KG he did that to. He might not be alive right now if he did that to KG...
