The site looks good. Clean and modern. You've done a really good job so far.
A couple suggestions.
Consider placing links in the page text to other pages on your site. One of the many things Google ranks is cross linking.
Example: Sponsors tab:
text says "If you are interested in sponsoring our team, please visit our "Sponsor Application" page! Any unanswered questions can be directed to
frc3525@gmail.com."
Consider linking the text "Sponsor Application" to the page or pdf that the text is referring to.
You may also want to think about using a "Contact Us" form instead of announcing the email directly on the page. It opens opens your email address up to SPAM crawlers and your email inbox may get bombarded by useless junk emails. Contact forms help with this, but aren't a sure bet either.
Keep up the good work!
