It's not that simple. They'd be getting >$10 million in cap space, and if they think they can get both Dwight and CP3, then that likely is the difference in getting both or getting neither. Getting some project big from France or some project big from New Zealand hardly looks good in comparison.
Can't they just amnesty Marion then? I don't remember them using that on anyone else yet. So that's $9.3mil gone.
Losing a pick just to save $1.6mil is hardly gonna make a difference in signing Howard.
