Not sure why people keep saying this. He's much more effective on the Jankowski line.
I mean, sure, we could leave Bennett on the top line and wait and see if chemistry develops, but why? That would mean intentionally playing multiple players on their off-wing with no real benefit. The top line right-winger is Micheal Ferland, and anyone playing in his place right now is just filling in. Why not achieve chemistry on the third line and have Stewart be the fill-in instead, and have everyone playing their natural position?
Ferland is also a player playing on his off wing... He's also shown minimal over the past month playing with 2 elite players.
February - 4 points in 12 games
January - 10 points in 11 games
December - 6 points in 14 games
So 20 points in 37 games. That's not nearly enough considering he is far less physical than he should be. I get consistency is an issue for him, but why is trying Bennett at 1LW for more than a brief stint so hard for GG to come to terms with.
Edit: For context - Monahan has had:
February - 15 points in 13 games
January - 9 points in 10 games
December - 8 points in 14 games
So 32 points in 37 games.
