On paper, Coach Rob Mendez sounds like any other football coach on any other field across America - passionate, authoritative, knowledgeable. But he's unlike any other coach you know-in fact, he's probably unlike any other person you know. Born with an extraordinarily rare condition called tetra-Amelia syndrome, Rob has no arms or legs. He moves with the assistance of a custom-made, motorized wheelchair that he operates with his back and shoulders. Many people look at Rob and see limitation, yet Rob sees opportunity - Opportunity to pursue his passion for football. Opportunity to change the way people perceive physical disability. Opportunity to serve as a role model for the hundreds of kids he's coached over the years. Told with both humor and frankness, Who Says I Can't takes readers on Rob's incredible journey, from his birth to loving parents who wanted to afford him every chance for happiness, to the emotional and physical hurdles he faced while seeking independence, to receiving the Jimmy V Award for Perseverance at the Espy Awards in 2019. Each day, Coach Rob rolls onto the field and shows his players that dreams are achievable when you show up, do the work, and believe in yourself. And after reading this book you, too, will believe that anything is possible.
