It's a staggering number, on a terrible team. There is no question, that he had a bad year. Before last year, he was an up and coming defensive D, with good mobility, physicality... not great at moving the puck, no offensive instincts of note. Keep in mind team goaltending was at 0.891 save percentage.... He was #3 TOI for them last year, with over 62% Dzone starts... on an atrocious team.
He played a lot with Gavrikov, and was a -10 as a pair.... Gavrikov moves to LA Kings, and has been a +13 since.
Peeke gets paired with Gudbranson, and Blakenberg after the trade... and they ended up being disasters together.
Obtaining him is a gamble.... it could work out very well, or maybe not. If you had asked me last offseason.. I would have been 100% for obtaining him. Now... I'd wait and give what we have a chance.
