Herm Edwards is used to inspiring his troops.
The former NFL coach and current ESPN analyst is known for delivering the type of inspirational talks that can make even the most unathletic of souls feel as if they can take to the gridiron and shred the competition.
Naturally, he was the right choice to coach a squad of celebrity do-gooders for the season finale of ABC's "Extreme Makeover: Home Edition," which airs this Sunday at 8 p.m. ET.
In the episode, the team heads to Pine Mountain Valley, Ga., to make over the lives of Jeremy and Jennifer Williams, whose son Jacob was diagnosed with spina bifida before he was born. The family's story became more complicated several years after Jacob's birth, when Jeremy, a local high school football coach, was diagnosed with Lou Gehrig's disease. Their house is crumbling and too small to accommodate the two disabled family members.
