We played NO last year, and they beat us. He had to scout us, and our players. He know what we do well, and obviously what our holes are. So he has one up over other people in really being able to evealuate our team.
That said, he obviously knows how to get the most out of the Dline. That was one thing that NO's had right.
Also, there defense and offense were both much better then ours statistically and that was even missing their best WR (Horn) most of the year, the #2 missed some time because of injuries, plus they missed their best weapon in Mcallister. Granted they won only 3 games, but they had a tough division in Carolina, Tampa Bay, and Atlanta.
I don't think he is the best person available, but he knew how to beat us, and knows our team better then our previous coach, who shall not be named.
