Last season, Hockeyanalysis.com has his Corsi For % at 52.4 and Fenwick For % at 51.9. NHL.com has his average shot length at 63 (not sure if any site has average shot distance of on-ice shots for/against).
For comparison's sake, Edler's on-ice shooting % last season was 3.63% (according to Hockeyanalysis.com). Among dmen who played 1000+ mins, 2nd worst on-ice shooting % was 5.29%, followed by 5.46% and 5.48%. The previous season, Edler's on-ice shooting % was 7.12% and the lowest (among dmen who played 500+ mins) was 4.12%. The season before that, Edler's on-ice shooting % was 7.51% and the lowest (among dmen who played 1000+ mins) was 5.24%. It's basically an extreme anomaly for a defenseman to have an on-ice shooting % beginning in the 3's over 1000+ minutes.
Over 800 on-ice shots on goal, the difference between an on-ice shooting % of 3.63% and 7% is 27 goals for.
I just don't know how the extreme anomaly can be (largely) attributed to anything except bad luck. He had a bad season but he wasn't actively sabotaging his teammate's shots while he was on the ice.
