No Cap in Started Franchise
To turn off the cap in a franchise you already have started get your team extremely close to the salary cap (100k to 0k works for me) but you have to be missing a player you need (ex. have only 4 WR) then try to go to a regular or pre-season game it will say something to the effect of "You need a WR" then give you a choice to sign one or have the CPU sign it, choose CPU. Then it will pause for a second and say "no cap room choose cancel to sign player yourself or choose ok to turn off salary cap permanately. "Its that simple warning though this will turn off owner mode for good

Help Lower Salary Cap (in franchise mode)
To help lower the salary cap,when you sign people sign them for 7 years and raise the signing bonus, it will raise your cap until a certain point then will lower it,raise it to the point when it gives you the most cap and there ya go as Madden himself would say BOOM

Various Hints-n-Tips
In Owner Mode, when you get to the Playoffs you should raise your ticket prices, food, merchandise, and parking over the expected prise. The Fans may complain, but they will pay up to see your team play in the Playoffs (You need to have the homefield advantage to do this). Also in Owner Mode (will be referred to as OM from now on) at the end of your season SAVE YOUR GAME, before advancing to the off-season. Take a look at your retired players, not restart your system and trade them off for some draft picks, or whatever you can get. NOTE--This will only work if you turn OFF the trade deadline option.

In OM your advisors may mislead you. When I raised prices they told me that fans were grumbling about high prices (Don't make them too ridiculous!). If you only raise them a few over the expected, fans will still continue to come. However, if you notice a considerable drop (over 5%) of people not attending you should hold a fan appreciation day. The best ones are the ones like tame atographs, team movies, etc. Anything that has to do with the team will be big. If you happen to see nothing that has anything to do with the team, just go back to the OM menu, and go back to the fan appreciation day menu. Each time you go back and forth you get new options.

You may not think that this matters, but it DOES. Each time you play a game look at the teams roster you are playing. Take a look at their weaknesses and strengths. Now go under coach options and see you gameplain to the opposite of the opponents teams strengths (ex. if the team you're facing has a strong running back, set your team to worry about the run more, if the opponent has a weak secondary, set you O gameplain to be passing). Now that you've done that go to management and tell all of your players exactly how they are to play. If you want to pass rush set you D-line to the pass-rush side of the bar, if you want them to stop the run, slide the bar to the other side. Do this to all of your players, and you will be a LOT more successful in your game.

In OM if a star player is starting to get old do not hesitate to trade him for draft picks. I suggest you do this. While in the short term you lose a star player, in the long term your rookies will be developed into stars when your opponents start to worry about getting new players. You will be one-step ahead of the CPU. For example, if you play as the Rams (go RAMS) you see that Bulger is much younger than Warner and will be as good with a couple more years of playing time under his belt. You should trade Warner for a butt-load of draft picks at the end of the year to the team that gets to pick first. I got all of the Cardinals picks for Warner, and 5 out of those 7 are starters in my second season, 2 out of those 7 are on the road to the pro-bowl, and my rookie CB, is nominated for the rookie-of-the-year award. Trust me, you need to do this.WARNING-Don't trade all of your star players, your rookies play better with a veteran to look up to.
