Auvitu has been fine, actually pretty darn solid for a bottom pairing guy. The problem all season has been the Klefbom-Benning pairing and recently, it's more due to Benning's issues than Klefbom.
Yeah ....
The Oilers had two top-four defenceman on IR on the verge of returning. So they claimed Brandon Davidson on waivers. In all six games since Davidson has been back with the Oilers he has had more ice time than Auvitu.
Apparently the Oilers coaching staff don't share your view that Auvitu has been pretty darn solid.
