Create a player named Max Stats. Put his number to be 99. You can now make his stats at the max. You can change his name afterwards and he will still have the stats.
When you are in a season or a franchise, get a player from your lineup, but not as good as your better players. Spend time just trying to find better players than you are using, like Carlos Lee, Normar, Sheffield, Gordon, Lowe , Nathan. Get one of them and try to find one of the best player on a opposing team's line up. Trade your new player for him, such as Martinez.
