Posters make the weirdest comps when it comes to the Lakers' lineup.
Reaves is a starter and has been the 3rd best player for the Lakers this year. Why would you compare him to Donte, a bench player who is maybe the 7th or 8th best Warrior? The comp for Reaves should be Klay or Wiggins, not Donte.
Why did you stop at 3? You could easily argue the next 3-4 best players on the court are all Warriors. Lakers are relying on Reaves, D-Lo, and Rui as their #3-#5 options, none of whom have ever shown anything in the playoffs before now (plus D-Lo and Rui might be defensive liabilities), while Warriors have Wiggins, Klay, Draymond, and Poole, all of whom have already excelled in Finals runs. Not to mention Looney and Payton who are playing their roles well. And once you get past Rui, the Lakers are stuck with guys like Vandy, Beasley, Schroder, and Brown, all of whom have been ass offensively so far.
I think if LBJ and AD are both healthy and able to go all-out, and the supporting cast makes the shots they should make, then the Lakers will win the series. But none of those are givens. Even if LBJ and AD are on, they're going to need some sort of help from the rest of the roster to be able to beat a team that has 4 players who can go for 20+ every game and a 5th/6th who will be defense and rebounding monsters inside.
