Anything is basketball that is within the rules. And nothing is overrated that works. And in any contact sport, he who can knock the other guy on his *** almost always works.
Yet if you saw Hakeem play at all you would realize that there was not a man on the planet that could chase him from the post, not even Shaq. He had a little jumper, would use it a few times a game, but NO player ever made him use it. Nobody ever made Hakeem go "oh, guess I can't post this guy, time to run outside and chuck a jump shot."
Jump shooting is easy and lazy. It is a giveup shot unless you are really tremendous at it. Its a shot every single member of this board can take. If you're a big with a post game, and Spencer has shown flashes of it, post game >>>>>>>>>>>>>>>>>>>> jump shot. More difficult (only atiny fraction of this board likely has any real ability in the post), more sophisticated, causes far more problems for the opposition -- we in fact saw that ourselves in the Portland game as Oden crunched us inside, our defense had to collapse to stop him, and then all of a sudden all of their perimeter guys were open to drain threes. But its hard work, and it takes dedication (like many things in life). If you just give up on it and quit at the first sign of resistance, then its never going to amount to much, and likely neither are you.
There are two essential unique things a big man, and only a big man, can bring that can key a good team -- dominant rebounding/shotblocking/interior defense on one end of the court, and dominant post play on the other (there are no dominant rebounding/shotblocking/interior defense guards, and have only been a handful of dominant post guards -- it has to come from your bigs, or nto at all). Spencer will never be a dominant rebounder/shotblocker/interior defender. That already sets him apart from guys like Hakeem, Robinson, or Ewing, who could have been 10ppg scorers and still been key centerpieces for their teams. So he HAS to utilize that post ability or all you have is another softie. This fascination of his with emulating Brad Miller is unnerving. Brad Miller has never won anything, nor will he as a starting center. He can't do those big man things. You can find better models in Vlade, Smits, Arvydas (who were unfortunately all bigger and stronger than Spencer). All those guys had face up jumpers, would break them out with some regularity. But they also all loved the post, and would establish that first and do their real damage there. That's where they became tough guards, and where they could create spacing for their perimeter players.
