I don't expect the Lakers-Heat to make 39 of 43 (91 percent) free throws like they combined to do in the Heat's 111-108 Game 5 victory on Friday. 
I do expect both teams to play intense defense and for the pace to be slow in Sunday's Game 6. These are two reasons why I like the Under. There are other factors, too, that point to a lower-scoring game than what the total indicates. 
Fatigue and being in the bubble for so long are considerations. The Heat have shortened their bench to just two reserves with starting point guard Goran Dragic out. Jimmy Butler is on fumes. Miami has to play a slow-down, half-court, slog-in-the-mud style. They have the mentality, coaching and guts to win this way. 
The Lakers' greatest fear of LeBron James and Anthony Davis not getting enough help was realized in Game 5. Except for those two superstars, the Lakers didn't get good performances from anybody else. LA's reserves were 5-of-22 shooting from the floor for just 14 points. None of them can be counted on. 
This puts tremendous pressure on James, who doesn't figure to make 15 of 21 shots from the floor like he did on Friday, and Davis, who isn't 100 percent. Davis is dealing with soreness in his right heel that was reaggravated during Friday's game. Bothered by that, Davis managed just two shots in the fourth quarter. I have no doubt Davis will play Sunday. How effective he'll be with the heel injury and with defensive ace Bam Adebayo guarding him remains to be seen.
