Oilers' roster cleaned out since Peter Chiarell took over

To say Peter Chiarelli’s finger-prints are all over the Edmonton Oilers roster is obvious.
When he got his first look at the Oilers’ 23-man roster in his first year as general manager in 2015,  he wasn’t in love with the opening roster, with winger Jordan Eberle out with a bad shoulder.
Change is always good. But from then until now, this has been almost a house-cleaning.
