re: DJ Durkin is the DC for my team now. What should I expect from him?

Not as familiar with DJ Durkin as these Florida fans like gator is but from what I've watched over the years is that Durkin gets a good pass rush going with blitz packages and puts his corners on islands. You'll need to recruit better for his system to work. Jabrill peppers will do well for you. Durkins talent at Florida is much greater than what you have right now. I'm sure harbaugh will get you going there though. I would expect your defense to be simple his first year or 2 with the lack of players Durkin and harbaugh have hand picked. Year 3 I would think yall become more multiple and run 3-4,335 stack, 4-3,4-2-5, and several nickel and dime packages. Year 1 I would bank on 4-3 with 3-4 looks if you have a hybrid OLB/DE that's legit.
