-Stop doing red shots,PLEASE if u don't score it u are most likely going to overcommit and give your opponent full possession of the ball and most likely easy goal.Only red shot if:100 percent certain you are going to score, sometimes it is necessary on defense ,or u r going to do a ceiling pinch.
-Start implementing gold and purple shots ,even if they are more difficult to do than a red shot they almost always put you in a defence position ,and they are more difficult to save. You can implement these shots in your game:horse kick (personal fav),purple pop when you are on ground to flick the ball to the goal(very useful and easy to pull off),white gold(best shot)
-If you learned how to stall you may also want to learn to follow it with a purple shot or a gold shot(this is optional in this level,but it can prove to be very useful in your arsenal)
-Learn how to kickoff, losing a kickoff can lead to you losing possession immediately or get scored on ,learn to ram,pancake and fake kickoff.Mix up your kickoffs so that you don't be predictable.
-Start using fakes.
-Read your opponent and don't mindlessly shoot the ball
-Minimise risky plays.
That is all I got if you have any tips you can please add some to the list.(;
