BTW- it should also be noted about the differences in the defensive units that RAC coached and the one Patricia leads. RAC got to coach a team of very experienced professionals. Rodney, Law, Milloy, Bruschi, Vrabel, etc. Patricia has been forced to coach virtual children in comparison. That's a big difference that no one is considering.
At no time in RAC's tenure was he using 5 rookies on a regular basis on his defenses. He always had at least 2 seasoned all pros in his secondaries. IIRC, EVERY LB was an experienced guy, and most of the DL. (and it didn't hurt that the DLman that WASN'T a vet, was Richard Seymour) This isn't to slight RAC's accomplishments, but before you make comparison's between him and Patricia, it should be on an apples to apples basis.
