I mentioned Ron Brown as the "obvious choice" for the continuity coach in a post yesterday, so maybe this thread is referencing that?
I mentioned Brown because he's the least "Bo's Guy" coach on the staff that a new coach would consider retaining. The other two are Cotton and Garrison, but I doubt they would be kept. Cotton for obvious reasons and Garrison because he's not a proven commodity and a new coach probably has a short list of O Line coaches in his hip pocket, and it's unlikely Garrison is on that list.
Coach Brown is the clear choice because he's well-liked by the vast majority of fans, he's a link to the Glory Days, and he's a pretty solid coach. If you have to keep a guy from the previous regime to help the players transition to your staff/way of doing things, Brown's a pretty good candidate. He's not likely to make waves in the meeting rooms, he's not going to drive players away subversively, he's just a get-it-done guy. He's pretty easy to get along with as well. That's important.
Someone mentioned Warren as an option in that thread yesterday, and I have no reason to believe he's not a good choice. I don't know much about his pedigree so I can't give reasons pro or con on him.
