Nagy and Brian Johnson aren't even in the same stratosphere when it comes to their relative "incompetence". Quite frankly, if Reid ever allowed the offense to deteriorate to the extent the Eagles did I wouldn't mind a sideline confrontation or two to wake his ass up. And you chose a really poor example with Kelce, since he's actually gone to the point of shoving a coach when emotions peaked, not to mention all his other antics. The difference here is there's enough mutual respect between players and staff to let those emotions recede and get back to business. By all accounts that's not a thing in Philadelphia.
