This may be the key.
But hanging onto a guy that the rest of the team, let alone the striving young D looking to break in, know isn't worth his spot is also likely to ruffle feathers, as I believe they say. How do you explain to Heinola / Chisholm / Capo that they're heading back down to a league they're too good for so the team can play yet another D who makes them worse. At least with Pionk some of the guys can remember when he didn't suck.
I feel like the signing itself was a favour to the big man -- get waived, and still make your guaranteed contract, or get picked up elsewhere and have another shot to play.
Maybe it's the injuries, or a natural plateau, or a combo, but it feels like the time to #FreeStanley.
Tho I take the point that in Jets Time, that point often gets an extra season or two.
