Speaking of the Belichick GM tree , his learning under Bill Parcells is what created him. So its weird I'm watching the story of the 1986 NY Giants team. The one who went to a Super Bowl.
The funniest story was the relationship of Phil Simms and Bill Parcells. The 2 men clashed at 1st back when he was 1st benched in 1983. Parcells admits he made a big mistake then and nearly was fired after a 3-13 season. Then the 2 men would argue on sidelines and swear at each other during games or things going wrong . Both admitted they were very firey type guys and let loose. But as Parcells admits he grew to like Simms for firing back at him and would defend him (we see clips of him defending Simms from critics in 1986).
Parcells also had ways to motivate guys through his critique of them. LT struggled to start that year after a drug arrest and was being mocked by media over it. He had struggled opening weeks and Parcells told him he was gonna change his name "Whats the Matter with Taylor" . Parcells kept on him and finally he too fired back at Parcells and started playing great. (he would end the year with 20 sacks and said it was some weird way to get his mind back in the game Parcells was doing).
