To execute an unfair trade with the trade logic on, trade many times. You can trade a 70 overall player for a 71 or 72. Once that you have that player, trade them for a higher overall player. Once you work that player up to someone who is about 90, it is as if you traded your 70 overall player for the 90 overall player. Note: If this is done a lot, teams will be more unlikely to trade for good players.
If you need more skill and less depth on your team, you may want to trade two of your average players for a good player. If you trade two players in the 80 to 85 range, you can receive a player in the 90s and a player in the 70s in return.
Go to Free Agency and sign on a player with about a 60 overall average. The game will state that the team already has a maximum amount of players. Sign off the player that you want. Then, go to the Free Agency and sign on the player you want onto your team. You can now have their players without trading.
Any time that you play a world team in franchise mode, you will receive new equipment to better your players. If you play a world team more than once, you can continue to gain equipment. This works especially well when you have completed franchise mode, and max out your team.
Once you have completed franchise mode, play the Moscow Wolves until you have enough level 5 equipment so that one player can have it all. The player you assign the equipment should be your Captain. Go to your locker room, and select "players". Change that players play style to "Speedster". He will now have an overall rating of 100.
When your team is down a player (for example, from hitting the goalie or fighting), your team cannot get another penalty. You can knock over the opposing goalie with a player and score on the open net with the other player. Note: This is easiest with two players.
Turn off the penalties and check the goalie until he has had enough and a goalie fight will start.
To win a fight easily, press Fire with at least one bar on the fire meter. Your wrist will go on fire.
