You have your opinion.. same as anyone else. I don't mind that one bit. No harm, no foul as you say.
As for Bradie and Lee.. if they can stay healthy as you said, i have no doubt they are both high quality players who can make alot of plays for our defense in the coming years, provided we do something about the lack of a NT on this defense.
I couldn't see us, unless a top prospect just fell into our laps, taking an ILB any higher than say the 3rd or 4th round in the next 2 years though. I understand we need to get backups who would be servicable if Bradie or Lee would go out.. but i'd rather keep Brooking for at least another year if for nothing else than to fill in and show the young guys how to play the game. He's been a great LB in this league for years and i think just the knowledge that he has to pass on would be invaluable to the younger guys.
I don't know where you were thinking about taking an ILB, but i feel like NT is probably our biggest need on this defense, along with safety.
Safety i would like someone in the 1st or 2nd round.. no matter what. NT, you could probably find a good one in the 3rd-5th, and i'd probably take more than one prospect at that position. Those are really the only two positions i feel we definately need a huge upgrade.
