It took 5 minutes to look that up it's not terribly hard. There's a thing called Google and Hockey Reference these days.
I don't even agree with your second point. I don't think Crosby would get that team that McDavid was on last season to a Cup Final even in his prime.
We saw Crosby when MAF was off his game for a few years and the Penguins routinely got beat in round 1 or round 2, take away the goaltending and Crosby would lose in round 2/3, especially with Draisaitl injured. He did so even with Malkin in years where he didn't have MAF or Murray holding the fort.
Pittsburgh has a huge advantage in goaltending and everyone knows it, you're not to even convince Stuart Skinner's mom let alone anyone on this board that he is a MAF tier goaltender.
Prior to his injuries, Murray was an amazing goalie too especially in big games.
