There production isn't comparable.Their 1st year contract percentage is irrelevant. They did not know the cap was going to jump up 4.5m the next year when they signed.
No, McDavid's is the equivalent of about 2m more for 3 more years. It's comparable if anything, just like their level of production.
And, yes, they did expect the cap to rise, because it did every year until the pandemic. So, measuring them by the first year of their contract taking effect is the best measurement. So, since you can't even acknowledge that, you don't even really believe in cap-percentage as an actual measurement.
