Every player has strengths and weaknesses.

DJ Young's forehand is one of the biggest weapons in his game, yet the Royals never really tested his backhand.

That's a mistake.

Before committing to a game plan, make your opponents prove they can beat you with every shot in their arsenal. If you never test the weakness, you'll never know if it's actually there.

Takeaway: Don't assume. Test every strength and weakness before settling into your strategy.
