I’m not a fan of nepotism. It’s inevitably in a family owned business, but it should be avoided everywhere else. Especially in football which is the ultimate meritocracy.
It’s poison to an organization creating hard feelings amongst employees who even if it’s not the case see the relative/friend as receiving preferable treatment. I don’t think it’s a coincidence that you saw a full scale exodus of defensive staff last year and then Greg Schiano’s quick departure. Would not be surprised if there are not more departures this off season.
Actually, if Bill wants what’s best for Stephen Belichick coaching career, he’d make sure his son got out of his shadow and made a name for himself on his own with another staff.
