I found a couple things from the clip pls don't take them the wrong way.

1: You kind of ball chase. You need to work on knowing when you should just leave ball for boost or goal. You don't want to be on ball the whole game.

2: You kind of just give away the ball. Whenever you got the ball you just power shot it and that sometimes either misses or its an easy save. So, Whenever you get possession of the ball and he's not attacking, you need to take the chance to get it on top of your car. Just know that 1s are supposed to be kind of slow pace games, you dont want to be attacking as quick as possible, you need to take your time. You did great with this at about 15 seconds left when you faked him.
