I tend to agree....but it is getting close. McDavid has racked up a lot of major hardware, which is hard to ignore. At the same time, it's hard to launch a forward to top 5 all-time when he hasn't even scored 1,000pts yet. This is why I always suggest I'm pretty sure he'll be ahead of Crosby by the end of his career, but not crazy to suggest he's not there yet.He's definitely ahead of McDavid right now.
I think people take longevity for granted a bit too much. Anything can happen. Crosby has aged quite well. There is no guarantee that McDavid will.
