5. Brook Lopez

The Milwaukee Bucks will have themselves a lot of money to worry about this offseason. Khris Middleton, Nikola Mirotic, and Brook Lopez are all free agents. The Bucks also just gave Eric Bledsoe a four-year $70 million contract. That will make retaining Lopez without bird rights difficult.

He has had arguably his best season as a pro this year. Lopez has become one of the team’s best shooters and a reliable rebounder. Milwaukee is going to have to do something clever to keep Lopez, who has undoubtedly been a massive part of the Bucks’ incredible success this season.

The Mavs will still need a traditional center next to Porzingis. Lopez fits that bill, yet he can still step out and shoot the ball tremendously. As a 37.2 percent shooter from downtown this season, Lopez can replace the shooting production that will likely leave this summer when Nowitzki retires.

Lopez and Porzingis manning the paint as well as stepping out for open shots will force defenses into one-on-one situations against Luka. The Mavs offense would be difficult to stop.

Lopez has been one of the biggest reasons for the Bucks dominant play all season. The perfect compliment to the Greek Freak, he also has shown an ability to play alongside another seven-footer who needs the ball in his hands to thrive. Dallas could form some lethal frontcourt tandems with Lopez flanking Porzingis.
