I'd definitely give it some thought if I were Cuban. As much as I hate the Mavs, I would love to see Mike D with Luka. Sure, Mike wouldn't get him to the promised land, but he would definitely advance.
To be fair, they overachieved that first season. That team played closer to their level the following season. Then for the past 11 years, the Mavs haven't exactly been a great team or expected to win much.
How much better are Mavs with Clinton Woods instead of Porzingus? This question would've been laughable last year.
And he also missed half the season anyway due to being made of glass lol. Not even getting your money's worth there
Mavs will have an interesting summer. Hardaway Jr will be a FA. JRich has a 11 million dollar player option that I'm guessing he will not renew. WCS will probably not be resigned. If they don't resign any of those three, they could open up about 20+ million in cap space I think. Maybe Lowry would take a 3 year 70 million offer?
Mavs need to put a proper supporting cast around Porkzingis. Trade Doncic for the right pieces while his value is still high.
