The Memphis Grizzlies have slowly managed to build one of the most formidable young cores in the NBA, and with this year's 17th overall pick in the draft, I think they have a chance to add one of the final pieces to the puzzle.
If I'm the Grizzlies, I'm not overly anxious to draft a win-now player as I think it'll take the team another year or two to become seasoned and understand how to win (let alone make it) in the playoffs. With that in mind, I would be looking for a secondary scorer that can take some of the load off of Ja Morant. With the 17th overall pick, the Grizzlies select Florida's Tre Mann.
Mann would make for the perfect candidate to eventually slide in next to Ja Morant as the team's starting shooting guard. Although he played more as a combo guard while in college, his efficient three-point shooting and three-level scoring potential would pair very nicely next to Morant. Ideally, he would be the Grizzlies' long-term replacement for Grayson Allen.
Mann is by far one of the shiftiest players in his draft class and is already an elite shot creator. That being said, more often than not, he was forced to create his own shot at Florida because of the lack of elite playmakers. In this way, Morant could make Mann's life quite a bit easier in that department given how good of a playmaker he is.
While Mann doesn't have great length and is only an okay defender, he would be big enough of an upgrade from Allen on offense that the selection would be worth it to the Grizzlies.
