Both teams performed about the same during the regular season, and it's not so clear at this moment which of these two teams will be eliminated first. In addition, there are still 2-3 games left until the end of the regular season. So there's a small chance that the Lakers and Warriors might not face each other in the play-in tournament.
That's possible as the Warriors have 3 remaining games, their ranking will go up, so they might be placed at the top 8 which means they won't be playing in a do or die game anymore. I'm sure they will do that as I think they could win the next 3 games.
Warriors next 3 games are
Trailblazers - road game
Jazz and pelicans, both home games.
Sure thing they can win all them, the toughest opponent on the list is only the Pelicans, but since the Warriors are at home, they have the advantage over that team. Jazz and TrailBlzers, this team are in a losing streak and probably have pulled out their star players already, so it should be easy for them. I guess the Warriors are just making sure now that they'll be in the top 7, so if they would succeed, they just need to play one game and maybe will face the Denver or Minnesota. It doesn't matter to them, I think the Warriors still have a chance beating those two teams but it would be better if they'll face the Wolves first.
