One thing the [Patriots] do so well is they evaluate themselves from a coaching standpoint and in evaluating players. But when I got there in 2011, one coach was here had worked there 10 years. Another had been there 12 years. Another guy learning to be an offensive line coach had been there for three or four years. The staff was such a tight-knit group and they worked together. It’s tough when you don’t have consistency in coaches. The philosophy and style changes. The play-calling changes. The scheme changes. It’s like starting over. That’s one of the toughest things from a team standpoint to go through. With the Patriots, you knew who we had and who they could trust and when you have that consistency it makes things so much easier.
