Lakers only problem is their bench but their starter is pretty solid right now. If AD will be consistent on dominating the paint, They will have a good chance to have a good run in then playoffs.
What do you mean by "problem" there?
Just because most players on the Lakers bench aren't that famous or popular, they are considered a problem. These guys are solid role players too.
They are just not getting enough playing time, since for now, the priority is to focus mainly on starters as they are catching up a nice spot in the post-season to avoid the hassle of play-in tournament. But this entire season, this second squad, when being executed properly by their coach, are all playing well.
