So, I've looked over the standings in the west and if the Lakers can win 2 of their last 4 games (thunder, Mavericks, Rockets, and Trailblazers), they've locked up the #3 spot in the west as they are up 2 games in the lost column from teams 4-8 and have the tiebreaker on all of them. Either they are division champs or they own the regular season head to head matchups with the teams in their division.
If they win just 1 game, one of the other teams would have to sweep all of their remaining games to knock them into the #4 spot. The Warriors would have the best shot as they have a very easy schedule in front of them (Suns, Spurs, Blazers, and Clippers). The Clips are really the only decent team left on their schedule.
EDIT: I meant to add......Man, there's a half game difference between the #4 seed and the #8 seed in the Western Conference.....whew......those teams are going to be SCRAMBLING. LOL
