You still don't get it - it's not just about Quality, it's formations and tactics too.
I can't buy 139% players either, but I can buy 99% players and train them up, then put my 105% team against the 120%+ teams and see if I can beat them - I'm batting 0.40 at the moment, but I rise to the challenge.
What you are proposing is just giving up, and wasting the potential of your team. Good luck with that, you'd be surprised what a team can do if the manager puts his mind to it.
