4. Luka Doncic and Kyrie Irving, Dallas Mavericks
Surprisingly, Luka Doncic and Kyrie Irving aren't the least experienced regular-season duo on the list. Doncic and Irving played in sixteen games together last season. A small sample size, with less than promising results.
The Mavs went 5-11 when both Doncic and Irving played in games together this past season. Although the duo had a positive net rating (4.6), their partnership did not result in wins.
However, the newly formed duo should not be at fault for the Mavs' shortcomings. Dallas sent away their best defender, Dorian Finney-Smith, in the trade for Irving.
With Finney-Smith off the roster and Irving in the fold, the new Dallas roster had to figure out a different play style. Rather than a roster constructed around Doncic, with spot-up shooting and solid defenders, the Mavs relied on a backcourt full of offensive firepower. But this roster lacked defensive stoppers.
This off-season, the Mavs reignited their porous defense, or at least attempted to. Dallas added multiple promising defenders through the draft, Dereck Lively II and Olivier-Maxence Prosper. Additionally, the Mavs acquired former Celtics antagonist Grant Williams via sign-and-trade.
With all these new additions and another year of improvement from Josh Green, look for Doncic and Irving to be surrounded by a team capable of making up for Doncic and Irving's shortcomings.
