The MIL team with Lillard and Middleton both healthy was a pretty good team.
I like Ingram with Giannis. And Giannis is at his best when he has a big center next to him (Poeltl). I think that is a pretty good start to a team. Quickley and the rest may leave them a good player away from a true title contender, but the team would a decent start.
(1) Ingram with Giannis
Is this not the same type of partnership that Ingram had with Zion in New Orleans? A bully ball PF who likes to drive and can't shoot well. That New Orleans team always underachieved. Ingram & Zion never hit high heights together.
On the positive side, Giannis is a much better defender & rebounder than Zion. So he will combine better with Ingram in those areas. Not sure about offensively though. Pelicans never had impressive offenses despite having 2 stars and quality supporting casts around them.
(2) Agreed on the defensive side of the ball. I worry about Poeltl's inability to shoot on the offensive side. Spacing will be a lot harder for Giannis without a Brook Lopez type stretch five to open up the paint for him. Bobby Portis served the same function in a smaller body off the bench for MIL.
I think you gotta get that stretch five for Giannis. That if you trade for him, you gotta think about trying to find a way to acquire one for him. Kinda like the LA Lakers are trying to acquire an athletic rim runner who can do alley oops for Luka. They just need this characteristic alongside them to unlock their individual offense.
