List of players I would 1 on 1 trade Giroux for:
Crosby
Malkin
Weber
Maybe:
Stamkos
Suter
Doughty
Keith
Pietrangelo
Tavares
And Giroux for Weber 1 on 1 is likely a lateral move anyway... so why do it?
As for Getzlaf not being on the maybe list... him and Giroux is a 'toss up', but Giroux is younger and can skate; and actually Giroux has done more over the last few years with less help, on a worse team, without one of the best goalscorers in the NHL on his wing.
I do not think that is overvaluing Giroux either...
the only two players in the NHL over the last 3 years with clear PPG difference over him are:
Crosby: 117 points per 82
Malkin: 106 points per 82
Then it is:
Stamkos: 95 points per 82
Giroux: 90 points per 82
Tavares: 84 points per 82
Hall: 83 points per 82
Kessel: 83 points per 82
No-one else has over 1PPG in that time... and of these 7 players Giroux is the best defensively.
