The mysterious reason (at the time) for Browner leaving was money, we all thought it was a consequence of Revis leaving and then becoming difficult to fit Browner in a zone scheme, but I read a interview with him still in the off season and he was all thankful for BB and Kraft etc but "when they asked me to take a pay cut I thought it was time to leave there", something along this lines.
So I think BB wanted him to stay, but at a reduced cost, probably because BB knows he is not a CB1 and maybe not even #2 depending on the match-ups, but he is solid in certain packages. So from a management point of view it would not be wise to pay starter money to a rotational player. I believe this team would be better with Browner still here, I have a feeling BB also knows that, but how better and at how much? We are entering in the final years of a lot of studs, it's a luxury we don't have now. If they can work something out though, it would be a nice addition. The Saints are hot garbage and will keep being mediocre for years .
