I don't normally agree with MJK, but I think the UFA rule change should be grandfathered in this season.
I planned my entire season around being able to trade UFA rights after the playoffs.
I like the rule otherwise.
Edit: after thinking about it, there is a way in the current rules to trade UFA rights, even after this rule change - so you may want to either close that loophole or rethink the rule
Step 1: Find a team to trade with
Step 2: Get them to trade you cap so you can sign the player (will have to throw in a token pick or whatever to make this legal with the current rule set. 9.99M for a 5th rounder anyone?)
Step 3: Trade the player to them, with the cap being returned (and the token pick coming back. High Priced UFA + 9.99 for a 5th rounder anyone?)
