This morning on NFL Radio, they talked about Dungy (and other HC's that didn't call plays), and highlighted how some HC's (like Tomlin) are 100% invested in the role while others are only 50% in because they are too busy calling plays. Tomlin currently has the Steelers at 6-2 and 1st in the AFCN with a QB duo of Fields and Wilson, and he has never had a losing season as HC of the Steelers, even with Kenny Pickett as his QB.
