Vibes were off on the Warriors all season. I really feel like Poole needs a change of scenery and frankly, get away from Draymond. Jonathan Isaac has played less basketball than Klay over the last three seasons but if he's healthy, he fills a desperate need in the team for a stretch big. Gary Harris will give them depth off the bench, filling the DiVincenzo or Otto Porter Jr role.
Also, there were rumors Magic were going to make a run for Poole before he signed his extension last summer. The Warriors may not think giving a pick is worth it but after this past season, a lot of people think his contract is too big. Warriors also seem poised to give up on their original plan to build for the future and compete at the same time so they may value picks less.
