The way Ovy scores goals--like, the actual skills he uses--makes me think he's going to keep this up for a while. I think he's going to be a 30 goal, 50 point guy, even when he approaches 40.
He has an outside, but legit, shot at Gretzky's goal record, IMO. Needs about 270 to do it, and, while I think that's a stretch, it's not completely beyond the realm of possibility, and I think it's a good bet to say he has another 200 in him.
If Ovy stays in NA until he's 41 or 42, at which point he'll likely just be a one-timer, but could still a decent pp2 specialist, I don't think it's impossible.
