Tyler Seguin's trade put the Bruins ten steps backward, which is a scary thought considering they remained Stanley Cup contenders for over a decade after he left.
The Boston Bruins have had their fair share of controversial decisions over the last couple of decades. It started with the Joe Thornton trade, and continued when they shipped young stars Tyler Seguin and Dougie Hamilton out of town in the early 2010s. It seemed like the Bruins were building a dynasty, and Seguin practically fell into their laps at the 2010 draft thanks to a first-round pick from the Toronto Maple Leafs.
