Saleh has been on the hottest of seats for 2 seasons. There's no chance at all Douglas was surprised by this. Johnson was on the phone with Rodgers the night before he fired Salih---and Rodgers also, comically, claims he didn't know.
Anyway, the Mara family doesn't have a history of being particularly meddling. Even if Daboll hated Jones, he could have drafted a QB at 6 this year and just rode out Jones's next 2 years. But he didn't....
Jones is Daboll's guy at the time of that contract signing.
