Max Garcia's cause: Pediatric Brain Tumor Foundation Why did you choose this cause? I've chosen to highlight the Pediatric Brain Tumor Foundation after learning that a coach's son at the University of Florida was diagnosed with brain cancer. His name was Colby Young, son to Bryant Young of the 49ers. Colby unfortunately passed in 2016. My best friend's daughter, Kimmora, was also diagnosed with brain cancer and is still fighting hard today. I know how difficult and scary this condition may be, as my mother had a brain tumor removed when I was a child. These people are very near and dear to my heart and I want them their stories to be heard. Team Colby, Kimmora Strong.

Shane Ray's cause: American Diabetes Association, Rays Awareness Why did you choose this cause? I have a responsibility given my platform to give to those without a voice and opportunity.

Isaiah McKenzie's cause: The John A. Hartford Foundation (elderly care) Why did you choose this cause? My grandmother was the sole person that raised me and through that, her friends — who were of course elderly and much older than me — became very important to me and I saw so many struggles the elderly face.

Aqib Talib's cause: Yellow Jackets United Why did you choose your cause? Because I was one of many kids always told how impossible it was to make it to the NFL. Too many kids are told what they can't do so we do the opposite.
