Probably close to zero at this point. With that said, around 5 years ago I thought Ovi would "only" score 725-750 goals. At that time, I thought he might have one more 45-50 goal season in him, surrounded by 3 or so seasons in the mid-30s and seasons in the low to mid-20s thereafter. Instead he has had 48,49,and 51 goal seasons in that period surpassing my expectations. Maybe he will find another gear and score at a higher pace for the rest of the season...or maybe not?
As it stands, he was starting to become more of a goal scoring specialist in recent years compared to his peak during which he created as many scoring chances for others. He is one of the greatest goal scorers of all-time (top 3 for sure imo), but not the greatest. That distinction belongs to Bobby Hull.
