Kerfoot (rookie but 1 year older)had 3 points less than Drouin and he play second line and sometimes fourth.Kamenev is Nhl ready good shape, ppg in ahl ,both play center.
I think Galchenyuk is better than Drouin it's ok for Galchy.
Kerfoot was riding an absurd shooting percentage this year and it started to go gown to reasonable levels at the end of the year. I think he's more in the Hudon category than Drouin. Kamenev I like a lot but again, don't see surefire top 6 upside in him. As depth additions both would be very much welcome though.
Galchenyuk is right now a better player than Drouin but the difference is Galchenyuk, who is still trying to find a fitting place in the lineup, is only signed for two more years whereas Drouin has five more years left on his contract. Both have tremendous upside but have yet to completely pan out.
