Montador worried about permanent damage enough to retain a Chicago attorney last month to sue the NHL for failing to warn players about the long-term effects of concussions, the Tribune reported. The list of former NHL players suing the league stands around 70, and growing, but Montador's name just became the most troubling one on it. Here was a 35-year-old man reportedly beaming to friends about being a father — Montador's son was born four days after his death, according to the Calgary Sun — and planning a future. Though his family acknowledged Montador's struggles with depression, others described a guy determined to carve out a post-NHL niche when tragedy struck.
