For the West, I think Spurs will make it, I trust coach Pop in crucial situation like this, then they will upset the Lakers. 
We can't deny that in terms of coaching, Gregg Popovich is really one of the best in the NBA, but this season I saw how the Spurs struggle and I think they will miss the playoffs this season, I'm going for the Pelicans as I trust Zion to give his best just to get his first playoffs appearance as a rookie.
I know the spurs have struggled this season so far but I just blindly bet on them as coach pop give help me wins a lot of times in the past so I owe him a lot, and soon this awesome coach will retire and he will be a respected coach for a the basketball fanatic like me.
There's no indication yet that he will retire but as long as he is still managing a team, I will always follow my heart, lol..
Last season, I bet on the Spurs to win against the Nuggets, it was a fun series for me although Spurs lose in 7 games IIRC.
Blindly betting, I think that's a good recipe for big loses, hehe..
Anyway, it's your money so it's up to you on how to manage it, but I think Spurs will not make it this time.
If we based the prediction below, we need some kind of miracle for the spurs to make it to the playoffs.
The San Antonio Spurs have a 2% chance of making the playoffs and a <1% chance of winning the NBA Finals
