Practice like its the Finals: Every possession, every second matters. No wasted possessions. Everyone's watching. There's pressure in the Finals and it's not for everybody. Some players don't even want the ball. There's money being wagered on the outcome -- a lot of money. Don't mess up.
Play like its practice: No pressure. It's just you and the teammates you see every single day. You're playing hard, focused on getting better as an individual and as a team. The coach is pushing you past your limits -- embrace it. You will make mistakes; that's why it's practice!
