It seems that a bunch of these kids on the rosters are out there to do the same thing. The few years I went out to play in the WSOP, it was during the Summer League, which was obvious when I wasn't able to count the number of dudes taller than me in a casino one one hand. I remember seeing Pavel Podkolzin (fairly sure I was the only "civilian" in Vegas who recognized him) scrunched into a seat at a Cirque show that I thought was lacking in leg room and he's a foot taller than me.
I'm not a big Okafor fan, but he's a more valuable asset than anyone on the Knicks roster... Noel is a top-5 defensive big for the next decade, if healthy. And if his feet don't turn him into the next Greg Oden, Embiid's upside is ridiculous. Throw in Saric, Stauskas (a heist), and 3 additional #1's (two of which could be lottery picks) and despite having a long way to go, they're at least in a position to build something positive.
To be fair, Hinkie is going to either need to take on salary or pay bonuses to everyone on the roster, because they'll be well below the salary floor once the cap goes up next year. And you can bust his balls all you want, but I'd rather be in the Sixers position than the mess the Knicks are in right now.
I think you're grossly understating the luck factor with regards to the players available in the draft and regardless, trading Harden for a bag of balls to avoid paying the luxury tax is a million times more egregious a basketball decision than anything Philly has done in recent years.
Perkins is sh*t and a sizeable downgrade from the likes of Cole Aldrich IMO. No need to sign a guy who can no longer protect the rim and shoots 45% when 90% of his shots come from < 10 feet from the basket. I'd hope they make a run at Sideshow Bob or Koufos instead.
