All true, i think we all realize that to score >300 goals after age 30 its going to take a generational level goal scorer to do so as its extremely hard to do. But we have to start realizing that Matthews is at least starting to make the case that he belongs in the discussion of generational goal scorer based on 8 seasons of data now, which is nothing to sneeze at, and the fact that is doing things that have not been done for 40 years (scoring 50 in 50 2 years ago, almost doing it again this year, on track to have the 2nd best era adjusted goal total of all time, and to date out-scoring ovechkin who is now considered the goal scoring goat).
Sure you can say this discussion is premature, but just like the ovechkin thread back in 2014 that asked the same question i think matthews has least done enough to now say that the possibility of him surpassing ovechkin is in the realm of possibility and is no longer something that can be dismissed as pure fantasy. No one here is claiming that its a sure bet for him to accomplish this, but there absolutely is a realistic path for him to do it. The league having higher scoring now is only going to help his case. All of this is of course predicated on him avoiding major health problems.
