Answer:
Practice more or get his head in the game.
Step-by-step explanation:
The coach of Connor would probably asses that due to a successful run in the past years, Connor must have lacked practice and hence would advice the same. Another assumption can be that the coach gets mad at him and pushes Connor to get his head back in the game and perform his best.
Another assumption can be if that the coach is like "Coach Carter", then he would try and figure out the distraction in Connor's life to get him back to his best form.
