We aren't playoff contender either way... I'd rather use the cap space to pick up first rounders or young guys with upside. And your cap projection is way off. Say it is $65 M... We pay Favors $13 M, Hayward $11-13 M, and Burks $7-8 M, plus Gordon at $15 M puts us at $46 M... Burke, Gobert, and the 5th pick & 23rd pick is another $7 M. Puts us at $53 M for 8 players... add in cap holds and we're right around $10 M in cap space.
The fact is cap space is an asset... Your trade makes bad use of an asset and really doesn't fit with what we are doing. The reality of our situation is that it probably does not help us to win 5-8 more games next year. We aren't close enough to make a win now trade. It would actually set us back to win an extra few games this year. Had we lost 3 more games this year, we'd likely have a better draft pick right now. Having Marvin and RJ lead us to a couple extra wins this year hurt the long-term outlook of the franchise.
I'd be on board if NO and HOU were sending a bunch of picks to make this happen.
