Its the numbers/behavior outside of those winning streaks that's concerning. Over GG's 4 year NHL coaching career (Dallas & Calgary) they are strikingly similar.
I get that Treliving wouldn't be too concerned with the Dallas numbers until they started to become visible in his Calgary stay. Then instead of turning out of it, GG turned into it. Sort of a self fulfilling prophecy.
I found these articles from Flamesnation to be quite interesting
