Granted, anything we "hear" that goes beyond second-hand information needs to be taken with a grain of salt. But, I wonder about the confidence level the staff has in Simpson as it relates to his psyche. Things we "heard" out of the offseason seemed to point toward him being "in his head" a lot and not mentally ready to play. Geeze, for him to be third on the depth chart just screams red flags for me.
**About his personality, play, both, etc.? You don't have to be specific, just a general idea that doesn't cross the line of bashing a player but enough to give information.
