A few points.
First. Most replays that the media are showing of the Horford incident do not talk about Horford with the arm lock on Delly. Not to mention the doctoring of the baseline footage. When they replay that part of the play, they completely crop out Carroll lying on the ground and Delly being dragged. This is clearly the media perpetuating a narrative and story to ask the question "Is Delly a dirty player?" He's not, but these idiots love talking about it.
Second, the three plays that have given Delly a "track record". They most certainly have. In all 3 cases, Delly is CLEARLY out hustling each player and they pay for it.
Gibson: Delly gets the better position on Taj and boxes him out. Taj assumes as the bigger, more physical player that Delly shouldn't have him beat in this situation. Out of frustration, what does he do? Shoves a few elbows at Delly and knocks him to the floor. Delly pins Taj's ankle. He's not doing any real harm here, but it's not a basketball play. Then the replay shows Taj clearly kicking his leg free and not actually kicking at Delly. I don't think Taj should have been ejected, but clearly Delly pissed him off by out hustling him under the basket.
Korver: Loose ball. Delly does what you are coached to do. DIVE for the ball and protect it. He dives for the ball and puts his body in between the ball and other defenders. Korver, the lazy player he is, goes for a loose ball like a pansy. Korver was injured by his own lack of desire for the ball. Delly wanted it WAY more and not only did what it took to get possession of that ball, but did what you're supposed to do. Be physical, get on the ground, get that ball. Korver injured himself by lallygagging. Korver set precedent here when in game 2 he sees Lebron driving the lane and runs the other way. He clearly showed that didn't have what it takes to win in the playoffs. Again, Delly just out hustling his opponent.
Horford: This is just like the Taj incident. Delly gets in the better position and boxes out Horford. Horford, another entitled big man, thinks he should have the upper hand here. Not only does he go over the back of Delly, but to keep Delly away from the ball, he pulls an Olynyk and arm locks Delly, pulling him away from the ball. Carroll is on the ground. When someone has your arm locked like that, it is natural for someone to try and stay level with your arm. If Delly just falls to the ground, there is a chance that his shoulder could dislocate. His natural response, keep your legs underneath of your body. That's why it appears as if he's leap frogging across the floor. He gets tripped up by Carroll, while at the same time Horford continues to pull him across the floor. When Horford finally lets go, Delly goes to the ground and bumps into Horford's leg. Horford drops an elbow on Delly's head/shoulder. Let's get real for a second. Horford drops that elbow. There is no question that was a Flagrant 2 and he's out of the game. You can't have guys just dropping elbows. That's not a basketball play. Imagine if Delly was in a worse position and Horford really connects with Delly's head driving it in the floor. THAT was a clear intent to injure Delly. But this is another case where an entitled big man feels like a PG shouldn't be getting the better of him under the glass.
Delly is clearly outhustling the Hawks in this series and it's pissing them off. I'm a little worried about tonight's game because I don't trust the Hawks. Just look at Antic's two armed push on a flying high Lebron. That is not a hustle play. That is just some bench scrub trying to be overly physical on a better player. Lebron even said in their press conference, if you're concentrating on Delly, you're not paying attention. You could tell he stumbled over the words a bit because he wasn't saying that Delly isn't a good player, but there is a lot more going on in the game than worrying about setting physical screens on Delly or elbowing him in the face on an inbound. Guys like Delly and TT have just wanted it more than the Hawks this series.
Hopefully they can close it tonight.
