Threatening to bench or cut someone who is playing poorly is pointless when that player looks at the PR and does not see someone capable of playing better than him. Making an empty threat is way worse than not saying anything at all. Sorry to say, as much as I am in favour of putting Burke out of our misery, I see no hope of him leaving before the end of the season.
In a perfect world, the GM would go to Burke and offer full HC pay for the rest of the season if he "resigns" and steps into his former job a defensive coordinator, either replacing Creehan or working beside him. Yeah. Like that is gonna happen.
