There are two competing scenarios going on right now: Houston and Thomas Robinson, and Dallas #13 pick + Carter. Both HOU and DAL are trying to clear about the same amount of cap space, and there are only a few teams with an expiring contract or the cap room to absorb the contract(s) outright. Since there are two teams needing cap help, neither is in a position of strength in the negotiations.
As i understand,Houston wants draft pick for Robinson,they are not mentioning expiring contracts.If they only want draft pick,can they get higher pick than the 28th?Is there any difference for their cap space if they draft & stash 28th or for instance 20th pick?Does a stashed player hurts their cap space?

As for Dallas situation,Cleveland seems to be the front runners to take their 13th pick.They are willing to take Marions contract.
