First, let's put aside the term "Hack-a-Shaq" and call it what it really is, that being, fouling a player and making that player earn his points at the line rather than get a more makable shot.
This philosophy is the same philosophy that the Celtics and most teams employ. But when you're dealing with Shaq or Reggie Evans or Ben Wallace the tactic is considered to have less integrity because that player is such a terrible free throw shooter??? I'm sorry that one is a head scratcher.
My old coach from way back used to have us shoot free throws until our shoulders hurt. His stance was they call it free for a reason. During the game you have someone trying to stop you from scoring, usually within 2 feet of you with a hand in your face. When you're at the FT line no one is guarding you, no hands in your face, no one trying to block the shot. It should be an almost automatic 2. And the only way to get that is by practice, practice, practice.
These less than 60% free throw shooters are the real disgrace to the game. To think that because they were big and talented and almost guaranteed to get in the league by the time they hit high school and didn't practice to improve this part of their game because it wasn't easy or "sexy" in a basketball sense is the real disgrace. These kids see highlight reel dunks, facials, unearthly blocks, and three pointers as part of the game they love and practice these until they can't move. But a free throw, never.
Well free throw shooting is also a part of the game. Always will be. And if players like Shaq can't hit over 70% they deserve to be fouled every time down floor. They think their size and dunking ability is a great asset to their team and should be used by their team. And they are right. But their free throw shooting is a huge hole in their team's armor and it is up to the other coach and team to not only see it, but exploit it.
"Hack-a-Shaq" is dull, boring, hard to watch, aggravating and effective. Instead of complaining about it perhaps people should be lamenting the fact that their heroes suck at a very, very important part of the game.
Every sport has an ugly part to it. Football holding penalties, backfield contact, and offsides. Baseball intentional walks, constant OB philosophy of taking pitches, and constant situational relief pitching. Soccer the whole [dang] sport. And basketball "Hack-a-Shaq". Al things that are done with the idea of trying to increase your chance of winning(in football 's case if you don't get caught).
They are part of the toatl game. Get used to it.
Oh, and if the Celtics play the Suns in the Finals, here's a guess, there won't be anyone complaining about the technique anymore.
