Who scores first nba system

So I am going to experiment with a who scores first in the nba game. It is a 7 game chase starting with $10 and I will go all the way up to $640 for 7 games. I will always pick the underdog for whichever side and will do research on who is on the jump ball as well.

I started tonight and hit on Knicks and now lost on the Kings. So tonight is :

Knicks- Win $10
Kings - lose $10
Clippers - Risk $20 to win $19

Follow along if you would like! I just wanted to keep up with it somewhere so here we go!

Clippers score first. +$19.00 

Game 1: 2-1

Sounds like a good system.
Attacking the underdogs to score first who will be plus odds all the time but in reality scoring first has got to be closer to a 50/50 prop

11/5 System Picks:

Timberwolves score first  +$9.50. (+$28.50 overall)

Hornets score first  +$9.00(+$37.50 overall)

Utah Jazz don't score first. -$10.00 (+27.50 overall)

Portland Trailblazers score first  + $20.00 (+47.50 overall)

Nice work my friend
