For thousands of lacrosse players across the country, a lacrosse stick serves as an expression of who they are. Take a look at a player’s stick—especially an advanced player—and you’ll likely get a good idea of their position or playing style. The best lacrosse players are able to wield a stick as almost an extension of their body.

But all too often, beginner or youth players make the mistake of getting caught up in how their stick looks instead of how it works, and that leads to on-field performance issues.

Titanium Lacrosse, a Midwest-based club program, originally posted this list of the top 10 mistakes lacrosse players make with their sticks last week on Twitter. It was compiled by Kevin Boland, Titanium’s director of coaching, a former three-time All-American at Johns Hopkins and five-year MLL veteran.

Without further ado, take a look at the list.

10. Too deep of a pocket.

9. Too low of a pocket.

8. Stringing your stick with a “V” or “U.”

7. Using more than three throwing strings.

6. Pulling mesh too tight at top, creating tug or whip.

5. Stringing a stick you can shoot hard with but can’t make a simple pass with.

4. Playing with a stick you have never practiced with.

3. Worrying more about the colors and not the quality of the string job.

2. Buying the most expensive stick on the market.

1. Thinking a new stick will automatically make you better.
