I mean I would accept Z if he really thinks he could do it. He would definitely help at a position of need. He may not be a great rim protector, especially at 40, but he would still be a big body and one that has had a lot of rest. Imagine that pick and pop back in CLE. However, I do think it would be very strange seeing as we just retired his uni lol.
Imagine at little stretches of a game a lineup of:
Kyrie, Miller, LeBron, Love, Z... 3 amazing outside shooters to compliment Kyrie and LBJ's ability to get inside and score or pop it out.
It would be weird, and I will believe it when I see it, but after this whirlwind of an off-season, I don't know if my brain can handle anymore shockingly good surprises.
