I'm not trying to defend Nico, but has it been confirmed that they offer Donic to the Wolves for AE and the Bucks for Giannis? If so, that does make it look like he tried to do a good trade. If the Lakers trade was like his 3rd or 4th option, then he should be held accountable and fired. If the Wolves and Bucks said "no", he should have just left it there. That is, if it was all his own decision to trade him.
If those rumors are BS about AE and Giannis, and the Lakers are THE only team he spoke to, then it's definitely shady as sh#$ and orchestrated by someone other than himself.
