We have a guy who splits time with the TEs in charge of special teams. It's anyone's guess as to how much time in practice and otherwise thought this staff gives to special teams. If they are giving it the time it deserves, then they are doing it wrong. That portion of the game can not continue to be ignored/neglected.
Booker's TE core has not exactly been lighting the world on fire either. It might be time to encourage Booker to seek life elsewhere. Even Davie, as shitty as he was, had excellent special teams.
