I would take that. Losing the faceoffs is tough but as soft as Connor is - his offensive upside is higher than EE's. And whatever you lose in faceoffs you gain in hits and blocks with Montour - he is going to be an animal.
Today:
Montour > Honka
Connor =< Eriksson Ek
In 2-3 years:
Montour >> Honka
Connor => Eriksson Ek
