I am pretty much done as well but in a different way, I am not angry about it anymore. I am just sort of like "whatever" about it.
Frost has a blank checkbook and I hope he uses it where he feels (if he really looks objectively) it is needed.
I would follow what Harbaugh, Sweeney and a few others have done...simply put go and get the best DC that money can buy.
I would also examine if I have weak recruiters on my staff, I don't know if they do or not but if they do, they need to be replaced. People sort of liked ripping on that DB coach last year (he is at Oregon now) but he can recruit. You need stud recruiters and I strongly believe your staff should be made of of at least 3 stud recruiters. I think you need a young one, you need a "faith" one and you need an "I can get you to the NFL" one.
