Sam is one of eight children from Hitchcock, Texas. Two of his siblings have died and one disappeared and has not been found.
Maura Mandt, executive producer of the ESPYs, calls Sam a "humble guy who isn't looking for any accolades."
"In deciding to give Michael this honor, while his courageous act of coming out is a part of it, the story is about the life he led growing up," Mandt added. "A man who has consistently lived his life with integrity, is never afraid of living this truth."
