G is the poster child for why you should expect top offensive players to play decent defense - because they CAN and still score. The idea if a player is good offensively they should get a pass on defense is a loser's mentality. Karlsson is a good example.
Great defense is skill and instincts, decent defense is primarily effort.
Losers pad their stats, winners do what they need to help their team win.
The shame for G is if Holmgren had started the rebuild in 2012, and built the team around G and Couts, he could have spent his career as a Flyer and had a shot at the Cup. Instead, by the time Hextall started in 2014, two years and asset value had been wasted, and he only had two playoff runs in his peak seasons.
