why did OEL’s skills apparently diminish so quickly?
OEL kept messing up his knee, which ruined his ability to skate backward and to pivot. At that point he was being walked by 4th liners instead of hanging with McDavid and Crosby types. He also somehow lost his wrist shot, which was the basis for most of his offense. There was a period where he was getting constantly rag-dolled into the boards and nobody on the Coyotes seemed to particularly mind which took its toll mentally and physically. I think it was a combination of bad culture and OEL being a bit disliked/checked out.
