You're right - he was one of the top players during the Subway Series.
For me it's not so much "hate" for Foote, for me it's that this team is deep on LW with high-end offensive talent.
Lafrenière, is a lock, Pelletier was also very impressive during the Subway Series.
Perfetti, and Foudy both have higher P/GP in their respective leagues. In fact, we have 13 forwards from the CHL with higher P/GP than Foote, not counting Veleno, Dach, Hayton, and 2 US college players.
I don't think Foote was on the Team Canada invitation list until he impressed at the Subway Series, that's why people are surprised to see him there.
If the game was played in NA with small ice surface, you could make a strong case for a 6-Foote-4 player. I'm wondering how he will transition to the big ice. Is he fast? Can he play a bottom 6 role?
