good point, wolf. for me, let's get the best available guy. he'd have to be willing to assess the talent and do what's best for the team. not just put his signature on the D. Whisenhunt is a staunch supporter of the 3-4, having come from pittsburgh. but he's changing over gradually in AZ as talent permits. 49ers, are running a mixture of 4-3, 3-4 on different sets.
right now, it's not the system that sucks but the players execution. either way, there will probably be 6 or 7 new faces on D next year.
