To get your created superstar's stats up easily, just go to 24/7 mode pick your superstar and then go straight to your calender, scroll down to wrestlemanina and simulate, when you do that you will have a lot of cash (p.s if you want to stop simulating days just press x on a day) then go to the shop and buy the fight package according to your superstars style it will put his stats up to 80 something, then just keep simulating all the years and eventually you will have a wrestler with an overall of 100! Hope this helps, to add me on psn im kemphall.
