I do agree with you to a certain point. I believe that why some people did not like the way you reacted is because we do not understand how the new retirement system works. It's difficult to argue about something we do not understand, so trying to understand it better might be the first thing to do.
In a previous, you replied that considering TSP and discarding salary to decide whether or not a player would retire is not the right way to achieve what was in the announcement. I liked your message even if I don't totally agree with your conclusion (if you want to, I could explain why). In a very rough manner, looking at salary would save mono-skilled players while looking at TSP would save multi-skilled players.
Today, I saw a 19-year old Hall of Famer who became FA, he had 74 TSP and a below 5k salary. I believe that, with the previous system, such a player would have retired. I don't have enough inputs to judge how good/bad the new FA system is. I still agree with you to say it looks strange.
Last point, I do agree that BB-Marin could have been a little bit more helpful to understand why a player retires or not, however, one of the big thing in BB has always been to figure out on things work and we, users, always did a good job at guessing. There is a sentence I like, I only know it my mother tongue so here is an attempted translation: "Learn, learn to know, know to understand, understand to judge".
