Knapp, 58, was riding his bike on Saturday in San Ramon when a motorist swerved into the bike lane and struck him from behind, his wife Charlotte Knapp tells PEOPLE. He was rushed to San Ramon Regional Medical Center, and later transferred to John Muir Medical Center in critical condition, according to NBC News and NBC affiliate KUSA. "My husband is one of the greatest humans I have ever known," Charlotte says. "Aside from being an incredible coach and friend, and touching the lives of so many, I think his greatest achievement has been his devotion to being an amazing husband and father." She continues: "The love he has for his family is unparalleled. We have three beautiful girls between the two of us, and they are three of the luckiest young women to have him behind them as their biggest cheerleader. He is a bigger-than-life man, and deserves a miracle if God is willing to bless him and us and that."
