Cavs:

PG: Garland

SG: Bol Bol

SF: Markannen

PF: Mobley

C: Allen

If you think about it, Bol Bol is really a 7ft 2 guard. He is struggling to find his place in the league due to a lack of strength to match up with other bigs. However, what sets him apart is his guard-like skillset at his size. Bol Bol can create his own shot off the dribble, and can also pull-up from three. The Cavs are running with a big lineup this season, starting Markannen at the 3, and it seems to be working pretty well. What if they decide to go all in on a unique, skyscraper lineup with 4 PF/C? It not like these guys are traditional big men, since as stated earlier, Bol Bol has guard like abilities, Markannen can space the floor, Mobley has the potential to develop a perimeter shot and can be an elite rim protector, and you have Allen who is already an elite rim protector. Defensively, it will be very difficult to score on this team with all the length and versatility at that length. Is it that crazy of an idea lol?

Meanwhile, the Nuggets acquire a young guard in Sexton, who can essentially be their Jamaal Murray insurance and can be an additional scoring spark even when he comes back.
