Having both be 'flexible' would make him a preferred candidate over a defenseman that would require Nurse to play full time on his opposite hand.
His age and potential cap hit should CBJ retain also fits Edmonton's needs fairly well. He's at a point in his career where extending him wouldn't be an overly expensive option also.
Oilers are smart to trial Nurse at RD. It does reinforce some urgency to fix a glaring hole but also the reality that they are somewhat disadvantaged with the volatile, trade market conditions to which they can't control. Utah for one example losing two RD have a significant war chest of prospects and draft picks to replace this position need that has scarcity and premium price.
Loved Provorov aș a junior with a lot of viewings of him. He seemed on track early in his NHL career to be a big minute top pair guy but he's kinda evaporated into an expensive question mark. Might he reset within a competitive environment and more manageable support role? Maybe.
The Oilers have substantive work to do to get this blueline up to championship level. The Utah situation whether they act on the trade market or not reinforces the risk involved of the unknown, beyond control reality to fix this roster composition problem through the external market route.
