I think he'd be a phenomenal fit with the Celtics, though I'd also understand interest in Jackson there. It just depends ultimately what direction the Celtics want to go in.

Do the Celtics want to improve immediately on defense or offense? Whoever the Celtics pick will reveal where they want to improve imo.
