8. Jalen McDaniels
A player much different from Cam Reddish that would still fit great in Dallas is Jalen McDaniels.
McDaniels finished last season with the Philadelphia 76ers and averaged 9.4 points, 4.3 rebounds, 1.6 assists, and one steal per game. Just like Reddish, McDaniels would give the Mavericks a big, lengthy wing. He is 6-foot-9 and has a 7-foot wingspan, giving him ideal metrics for defensive versatility on the wing.
He has good athleticism and can switch onto guards. McDaniels uses his length to disrupt everything and always competes on that end of the floor.
Offensively, McDaniels is a good cutter and a solid finisher around the basket. He often uses back cuts, which Luka Doncic would love, and he can also be used as a screener in the pick and roll. McDaniels can also knock down an occasional three and stretch the floor when he needs to.
McDaniels shot 40 percent from three during his 24 games with the 76ers on 1.3 attempts per game. He has a career average of 34.5 percent. McDaniels isn't going to be the player that comes in and knocks down a bunch of threes, but the defense will have to respect him from out there.
He is also a good scorer in transition and is crafty around the bucket. His defense would make him a glue player in Dallas, and you can never have too many young wings.
