Correct that's a good word to use here manageable. Agree with you on Mo. Its possible that when they loose Mark Barron in March that Mo could slip down some into the position Barron played when needed. Yes, McDonald is a future star playing strong safety need to keep especially if they loose FS Rod McLeod to free agency.
Your Brockers comment is interesting. I have been looking hard & posted several times about those very talented NT/DT prospects in this up coming draft. I have no ideal how Fisher feel about Brockers & the $$$ Brockers is sure to warrant next season at this time. The future cap $$$ needed to sigh a UFA DT like Aaron Donald (100 million?? Suh like) is sure to enter the picture in the Brockers contract thought.
A rookie Nose Tackle is a present need with the loss of Fairley how would it look with the loss of Brockers next yr at this time. I tend to think your "he's a player that can be sacrificed" has some serious merit if there was a talented rookie drafted this May. if not Fisher will be in one huge sour pickle in dealing with a UFA Brockers.
Eh. I think Brockers can be replaced by a reasonably priced FA next year if he walks. He's an important role player but you usually find reasonably priced run stoppers. But I like Brockers. I'd like to keep him. Price has to be right, though.
