Bill Parcells and Tom Landry are legendary in NFL circles, the fire and ice of the coaching profession.
Everson Walls has a perspective few can offer. He played for both men.
"Both are tough coaches,'' Walls said. "They didn't believe in giving you a break. But Parcells would actually talk to you as a person. He was like Jackie Gleason or someone, saying 'Hey kid.'
"He didn't look at you, at least at me, like Tom did. Every time I talked to Tom he was like, 'oh, what is it now?'"
Walls pauses for a second to smile.
