What is he going to say? "We brought in Bogosian to sit on the bench, we think he's garbage". Lol come on the quote means nothing.
He's [significantly] worse than all of Rielly, Muzzin, Brodie, Dermott, and Holl. I only didn't mention Lehtonen because we have no idea how he will translate. If he plays like a top-4 guy like some predict how is Bogo going to find a spot in the lineup over him?
He's here in case Lehtonen can't cut it, we have to trade one of Holl/Dermott, we want to play 7D in a game, or if we have injuries. Him playing in our top-4 would be a mess unless he has a randomly good season... which would be strange because he hasnt had a slightly above average season (or better) where he played at least 22 games since 2016-17 (and only has two in his 13 year career).
Aka he has had stretches of being an above average defenseman (2017-18 - 18GP & 2014-15 - 21GP) but for the most part he could barely be considered an average defenseman in the NHL.
