The Edmonton Oilers currently have arguably the worst contract in the league in Jack Campbell. It seems as though he may never play in the NHL again despite the fact that he still has three years remaining on his contract that carries a 5 million dollar cap hit. As a result, a buyout may not be a feasible option.
Based on the current NHL buyout rules, a buyout of Campbell would save the Oilers some cap space over the next three seasons, although they would still need to replace him on the roster. The team is unlikely to stick with Calvin Pickard as their backup going into next season. To be specific, a buyout of Campbell would save the team 9 million dollars in cap space spread out over the next three seasons, followed by three years of buyout penalty, that would effectively be negative savings.
Unfortunately for Campbell and the Oilers, it seems as though he is simply not an NHL level goaltender anymore. In fact, he seemingly is not even an AHL level goaltender as his struggles have continued since being sent down, if not straight up gotten worse.
