I challenge anyone to find a trade that took a team like our current one (medocre-ish)that actually transformed them into a different tier. I suspect any of the candidates will be ones where there were enormously bad downstream consequences like taking on a huge long term contract for one good year. We need some perspective on what trades can accomplish. They are generally more in the nature of tinkering.
Now if you're an actual title contender, that tinkering might be all the differene
If you want to transform a mediocre or worse team the frustrating fact is you need to do it through drafting and development. DOn't expect FA to be the answer. WHy would a FA choose a medicore team (especially NY with high taxes) when they can get the same money from a contender. It might happen but don't get your hopes too high
For our part, we have Obi, IQ, Grimes, Deuce, Sims and the mysterious Rokas in two years. We are trending well. All are talented and all seemingly have their heads screwed on straight (under-rated attribute)
You can complain about the FA adds but they were all generally quite good calculated risks as the price. Even Randle.
