You can harp on the "cap percentage was invented for McDavid" thing all you want, and you don't have to believe me that it isn't remotely true, but I do remember Dom also telling you that was completely wrong and he's much more believable than any of us.
The whole "cap percentage" was invented for McDavid is a farce. All you have to do is look at the structure of the CBA. Things like offer-sheets go up as the cap goes up, the maximum salary goes up as the cap goes up.
At the start of the cap era, if you offered 5m in an offer-sheet it was 4 first round picks. 5m was a lot. Now it is almost 10 million dollars in an offer sheet for 4 first round picks.
