Trading in the NBA is so different than any other sport. Trade away a draft pick and a decent player for a guy you're going to cut, so you can free up a little cap room. It flies in the face of common sense, but yet, because of NBA free agency, it happens all the time.
They may end up keeping him for this first year, just because it would be expedient cost wise, and he would be a good enough fill in for a 5th guy on the floor if needed. Who knows? Maybe he'll impress in camp enough to stick. I agree with the 50% though.
On radio last night there was some talk of them not even bringing Leuer to camp but instead just cutting him so they can dump a portion of the contract to free up some money. Not sure of the financial details or if the radio guys were just spewing crap.
Lots of theories out there as to what they'll do. I don't think it will take too long before we find out. Who knows? He could even be involved in a trade that would include a decent player, for more salary dumping. The NBA works in mysterious ways.
