Early in Backstrom's career Datsyuk ruled the Selke voting, and young guys like Toews, Richards, Kesler, Staal, Bergeron, Kopitar, Backes were all considered better defensively.
In the recent past Bergeron has ruled the Selke voting, while veterans like Datsyuk and Hossa still garnered votes and Toews, Kopitar, Kesler are still considered better. And now a younger crop of guys like Barkov, Coutourier, etc are slipping in ahead of him as well.
Being a fringe top 10 Selke pick is not a slight. It is actually probably an accurate assessment of Backstrom's value.
