Create a superstar. Duplicate him thirty times. Start GM mode. Turn off every 
superstar, and only leave on the created superstar. The other two brands will be 
left with the CAW at 20 popularity. Turn on the superstars again in the 
available draft the next week. When they become available, sign them, and you 
will win the ratings easily.
Send your superstars on trophy dates until their popularity reaches 100. Once it 
does, it usually stays there and will only come down a point or two. When all 
your superstars are at 100, you can just maintain the ones at 99, 98, etc. This 
will give you easy four star match ratings. Have as many rivalries as you can, 
and you will get five star match ratings a few weeks in.
