This highlights incompetence of RB FO and also coaching. Yes, Murillo had a tough year, where he made some boneheaded mistakes, but still contributed a lot, and was the best RB on the team. Year before he was an all star and still very young. Played well for his NT team. Mistakes were correctable too and talent undeniable. So, what do we do? Trade the youngster away after one sub-par season. He immediately wins starting spot on a team way better than RB. Can't say I am surprised.
It's not as simple as one subpar season, apparently he became a huge problem in the locker room.
