Matthews has 30 more goals in his first 8 years than Ovechkin had in his first 8 years. You're wrong about this and just can't bring yourself to admit it. You've picked a hill to die on for whatever reason. By every imaginable metric, Matthews has been the better goal scorer. The only reason he almost certainly won't match Ovechkin's totals is OV's freakish longevity.
Come on, you can say it. It will likely feel good to admit it. Otherwise, you'll just keep moving goalposts to some other intangible. Seen this routine many, many times my friend. My online posting goes back to the mid-90s Usenet days. All I have to do is keep posting inarguable facts (and I double-check them first).
