The Lakers can only hope for any success if LeBron performs as well as he has in the past and Davis stays healthy during the regular season and playoffs. By the way, some news sites say that this season will probably be LeBron's last chance to win a fifth title in his career because a lot of players on the current Lakers roster will become free agents next offseason.
Bron accuracy is in the perimeter shot is not that good anymore as well as his dominance in the paint. I believe his age is already slowing him down so his teammates need to step up big time if they want to win championship. He is not the Bron before that can carry the team single handedly.
I think they have the best shot last year to win the title if only Anthony Davis become more active on getting the ball to dominate the paint since he is very effective when he is active contributing. His on and off game makes Lakers short against Nuggets while they already beat GSW which is very tough opponent too that time.
I would disagree though, if ever they will have a good shot, it could be this year as they revamp the team and now they have a good shooter from outside in Prince. Of course it will rest on the shoulder of Lebron, but we haven't seen him slowing down, and so I doubt that he will suddenly gets old this season and no longer in his prime.
Anthony Davis looks good in their pre-season game against the Warriors. Although we can't just judge him by a game and it's only pre-season. But it seems that the Lakers is so confident with their current lineup that they might exceed our expectations for them this season.
