Will there be wide-spread holdouts from the post-CBA rookies?

I agree that the owners probably wouldn't agree to it. That's why I also suggested limiting the percentage of cap that can be spent on one player. While your top QBs would fight against it, it would free up more of the pie for the rest of a team's roster.

Or why not implement both? One contract is exempt from the cap but can't exceed a certain amount. Say 18% of whatever the cap is for that year.
