I started getting into the NBA around the time that Kemp has begun establishing himself as a star player. Whilst I wouldn't probably pick him ahead of Barkley or Malone, he was definately a quality player.
(Remember the Reebok shoes? The ones that looked like a zebra crossing?)
He had some spectacular highlights, heaps of alley-oops. Regularly the Kemp-Payton 'oop would make it into NBA Action (yep, australian's didn't get much NBA on TV back then and NOTHING now). I also remember the dunk contest where he pretty much blew it. Did he only make one attempt? I'm not sure.
My favourite one was an alley oop from Payton when after he dunked it he grabbed the rim for a second and pointed at someone in the crowd. Don't know why, but I guess just being able to do that is pretty spectacular.
Cheers
