I was being hyperbolic to make a point. I don't think Loggains is literally going to sit in a corner quietly playing with Legos all day.
He's just not going to be the primary guy in Sam's development. Building on what Derek Smalls said, Gase has to be more aware of the demands on his time here than he was in Miami. Loggains is the guy who will fill the role of being in charge during practice while Gase oversees the team, and he'll certainly work with Darnold on learning the offense, but at the end of the day, this is Gase's offense and I highly doubt he's letting anyone else run it.
