i dont see what the mystery here is
you think beane is just following his own vision of how to build a team...that he learned from another GM who was similarly following his own vision? lol thats such a convoluted thought process
panthers were built in the image of rivera, himself a defensive guy. his gms built the roster accordingly
similarly his former dc turned hc in buffalo asks of his gm a similar approach. the idea that beane is out here just lodestoning his way around roster construction is wild
