Here's why the Toronto Maple Leafs work is far from over after signing Sergei Bobrovsky

The first few hours of NHL free agency saw a flurry of signings, but one of the most intriguing involved the Toronto Maple Leafs putting pen to paper with two-time Stanley Cup champion Sergey Bobrovsky. The 37-year-old is headed to Toronto on a three-year deal worth $7 million a year, which, for a goalie who has won two Cups in the last three years, is one heck of a deal. However, this deal may not be as foolproof as you'd think given Bobrovsky's resume, which includes a pair of Vezina Trophies.
