I can see a team desperate to make a splash and join the ranks of the "contenders" possibly overpaying for him. I'd include Atlanta and Minnesota but both teams already emptied their draft capital war chests.
Just throwing stuff at the wall here.
Denver has Jamaal Murray, and giving him up for Irving would almost be an overpay right there when factoring in chemistry etc.
Toronto has all its own picks, could send out FVV, and seems willing to swing for the fences.
Chicago can include Lonzo Ball, but playing DDR off the ball isn't the best use of his talents, and LaVine didn't re-sign to be the third option.
New Orleans can match salaries with McCollum and has extra picks to throw in.
New York has a bunch of extra picks now and has plenty of expiring ballast in Rose/Burks/Noel (all team options in 2023-24). They might be able to meet Brooklyn's asking price themselves without having to involve any other teams.
