Here's the thing: LeBron James returning to Cleveland always means something, even if it's just a regular season game in April. The key matchup to watch will be Donovan Mitchell against D'Angelo Russell; Mitchell's averaging 26.8 points this season, and Russell's recent scoring surge (22.5 PPG in March) is a big reason the Lakers are playing so well.
The Lakers are red-hot, winning 8 of their last 10, including a big one over the Bucks. The Cavs, meanwhile, have been a bit up and down, dropping games to the Suns and Hornets recently, though they did handle the Sixers without Embiid. I think the Lakers' momentum, and LeBron's extra motivation, carries them. Lakers win this one, 118-112.
