Lakers are 14-2, but I don't think they are as good as their record right now. They have had a ton of close games against inferior teams...Even more, many of those teams jumped out to double digit leads, and they had to come from behind to barely win.
Lebron and AD are great, but there's really no one else contributing consistently. To put the burden on those two for an entire 82, it's not a question of "if", but just "when" they will have injuries.
