Holden requiring waivers is an enormous reason to keep him. Despite his shortcomings he's still an asset that has some legitimate value. If you waive him you lose him for nothing, and that would be ridiculous. Pionk spending a year in Hartford would be fine. He's a good prospect but he can still mature down there. Graves has less to gain from more time in Hartford, but it's preferable to him serving as a spare defenseman, in my estimation.
Staal is the real impediment here, but that's been beaten to death.
