Like you say, the only way I can see this rumor being true is if Olshey has lined up another trade that moves Nurkic to bring in another major talent. Whether that would be Davis, or a lesser move like Love or Griffin, I think it would be Olshey going all in to try to win big in the next couple of seasons. I have a hard time seeing how that happens, but if he can pull it off, yippee!
Let's assume we were trading for Love since it would take likely take less to get Love right now than Griffin and Detroit has Drummond so I doubt they'd be requesting Nurk. If we are pursuing Gasol because Nurk is involved in the Love trade, is that even a good move, lol? We'd be talking something like Turner and Nurk for Love? Yikes, I don't like that one but I'll continue to play. So then we call Memphis and offer what? Leonard, Harkless, Trent/Simons, and a 2019 1st for Gasol? I guess I could see those other teams doing that but what does that leave us?
Dame, CJ, Layman, Love, Gasol
Curry, Aminu, Collins filling out the 8 man rotation
Baldwin, Stauskas, Simons, and Swanigan for the deep bench
I guess we'd have 3 open roster spots to to add buyout guys or for other trades. If Love and Gasol were 100% healthy it might be decent for this year and mayyyyyybe next year if Gasol opted in but overall I don't think that is really much better than we currently have and we'd have no real way to replace Gasol when he leaves or gets too old. You'd have to really believe that Collins would for sure be our center of the future because having Dame, CJ, and Love pretty much makes cap space an impossibility.
THIS IS NOT A TRADE SUGGESTION! I'm simply seeing what it would look like to play out this scenario.
