1.35 P/60 in his first year in Montreal isn't exactly encouraging. It's hard to do as a fan when you're tanking, but getting attached to players who only put up decent-ish counting stats while playing huge roles on a bad team usually doesn't turn out well.
He might improve some but I don't think he's the team level improvement you're looking for if the expectation is to be an 80+ point team this year.
Put it this way. He's probably not going to be one of your top 6 forwards by the time this rebuild is done. We had some similar level young guys the last time we were terrible and they weren't bad players, but by the time we got good the Bozak's, JVR's, etc were nowhere near being top 6 players for us and left the organization.
