There is no opinion about it. The 5 best goalscoring seasons in league history for a +35 year old player are:
Bucyk:51g 36yo
Alfredsson: 40g 35yo
Selanne: 40g 35yo
Esposito 38g 35yo
Messier 36g 35 yo.
Bucyk had Orr. Enough said.
This is Ovis 35 yo season and it's shortened. He only has 14 goals. He's 174 g short. If you think he's pulling 3 50 goal seasons plus change in a row out his ads at 36, 37, and 38, good luck. If he does it then he is The GOAT.
The way i see it, if he is doing a 4 year contract. If he is up to 730 this year, it takes 4x35 to be just 25 goals behind. Doesnt sound that unreal, does it? If he has just one 45 goal season more in him, he needs to put 25 goals at 39.
If he has ~30 goal season under his belt at 39/40, you think he just bails out being so close? Miss out on being greatest of all time. Miss out on being absolute national hero in Russia.
So, all it takes is averaging 35 a season for 4 years. I Believe.
edit. Actually i think if he gets anywhere close to 50 range before his 40s, he is going to grind anything there is to grind, full Jagr/Chelios/Selanne mode. And Caps will let him to. After all, its an unbreakable record. You dont quit on it, unless you just have to (injuries, just being too far to catch). I think anyone who thinks Ovie will retire at 40y being 40-50 goals behind is just hugely under estimating the magnitude of breaking the record.
edit edit. Its really just hitting me. If he plays up to 42, all he needs to do is average 27,5 goals a season. Selanne still scored 26 at that age. Jagr scored 17 at that age. Even Chara managed to score 5 goals at 42. It really takes a career ending injury or horrible regression for Ovie not to get there, in my opinion. 9+35+35+30+26+24+16 and its done. Im definately not betting against Ovie on this one..
