I believe that the tweet was not meant to help his cause in the negotiations room. I believe that it was just sent out to show everyone that he was having a good day.
Though he did bring the Ravens into the tweet, I think he was trying to make a joke that people have taken very serious. And I don’t blame them. Ed Reed needs to be a Raven next season for that defense to stay at the top of the league. Despite having such a strong all around defense no one can convince me that they are anywhere close to where they are without him. Reed and the Ravens need to step up negations and get a deal done so both will be happy and move on to training camp. With a new Defensive Coordinator it is important that he takes as many reps as possible in the coming month.
However, if they do not do this and Reed does retire, I doubt if you will see too many AFC North fans shed a tear for his departure. Though he is a great player, one of the greatest safeties of all time, not having to worry about the ball hawk when playing Baltimore would be a nice change of pace.
