I think the only way Utah is involved in a Portland/Dame trade is a three way with Philly. Philly trades Maxey to Utah, Harris to Portland. Portland sends Dame to Philly. Utah sends pieces and picks to Portland.
That would give Portland picks to rebuild with and an expiring asset in Harris they can trade. Utah gets Maxey, a great shooter and 20 ppg guard. Philly gets Lillard. This is probably the best trade Portland can get.
It gives Utah a very young 20 ppg player for their picks and Philly gets another person to try to win with Embiid. But, I'm not even sure Utah can do something like this with Collins now.
