Jason Allen said one reason for his growth is because Mike Nolan's defense ``fits me the best'' of any system in which he has played: ``There's a lot less thinking. I get to react.'' And he listened to Parcells, who told him: ``Take the same mentality you use on special teams and use it on defense.'' Allen said ``it took me a little longer'' to develop not only because he switched between safety and corner, ``but I had three different coaches'' and some told him to stop using techniques he learned under the previous coach.
