No, the problem, Throw More Waffles, is that much like contract discussions where people like to cherry pick the best contracts ever to compare to and declare everything else "unprecedented dramatic overpayments", you're similarly cherry picking a few of the highest producing players in the playoffs ever, ignoring the external factors and context that led to much of that inflated production, and suggesting that everybody needs to match that, no matter their own unique situation, or they are bad playoff performers.
Matthews and Marner are point per game or higher in the playoffs on their current contracts, while facing +0.70 GSAx per game goaltending and 3 straight cup finalists, and while providing elite defense, PKing, etc.. You could do a LOT worse. I've yet to see anybody look at how it actually compares historically. I've just seen people do what you did here, and automatically declare it as bad because the points don't match what your specifically chosen player in situations much more conducive to production did.
