Contracts that expire this year are hard to say they are the worst. To me the worst contracts in the NHL are players who will make 7 million or more to the time they are 39 years old. If only I had some recent examples to draw upon...
Having Seth Jones on here and not Darnell Nurse is criminal. These might be the most overpaid players but not necessarily the worst contracts. Buffalo is probably happy to ride out a deal with a guy like Okposo, Lucic and Monahan are certainly worse because of the cap pinch in Calgary but the one year deals aren't so bad for teams that can afford it.
