As much as I appreciate that idea being throw out there, it's something that I think most will be against. General consensus seems that people want the lesser teams to have first opportunity for the higher priority free agents, which does make sense and is 100% understandable.
This. That's the conclusion they reached in the official league, and I think it's almost even more important here. I don't think disallowing free agent signings entirely is necessary (I just said I'd be ok with it...as I don't care one way or the other). The only thing I want to make sure of is that the system isn't being exploited. If you haven't played in a Madden league before, it might blow your mind the lengths people will go to to gain an advantage.
We've seen people offering maximum length contracts with the knowledge that the contracts are backloaded and the franchise would never last into those seasons, we've seen people cut and re-sign players, again to reap the benefits of backloaded contracts where the cost for the first few years is the least. It probably sounds lame, but there are many times I long for simpler days of just "this is your team...do the best you can".
Having said that, the only reason at all I wouldn't just do what the official league is doing of waiting until Week 4 of the regular season to do free agency (based on record) is just because we're going to have some CPU teams who could sign some of those players. By that same token, we're playing on All-Pro, which some have felt is "too easy"...so maybe giving those CPU teams a little extra help isn't a bad thing.
My number one priority over all else is just keeping things as fair as possible to everyone involved. It's hard to determine skill level before we get started (though, for those who have been in the league several years, we have a general idea)...so other than outlawing free agency (even temporarily) or just doing a random selection order and attributing any unfairness to "bad luck", I'm not sure how many other options there are.
I absolutely appreciate the input though. I'm trying not to rule unilaterally on these things...but it seems to be generally slow goings in all Madden leagues so far this year. Not sure why that is.
