I started in 2001, as far as I am concerned other than creating my dad as a character and turning on commissioner mode, I have not made any edits to any other option in the game and now I am in season 2007 so 6 years in and there are several teams that literally have "-" as their salary cap or another insane instance for example is the Minnesota Wild who have a current salary of $798,820,972 and the Colorado Avalanche being at $864,418,354 and the weird part is, they don't have anyone on their teams even close to like a million dollar contract, I only noticed when I saw that the ottawa senators were absolutely stacked and then saw that, Boston traded absolutely everyone of value or that had a contract for just draft picks, Thornton to Anaheim for a 3rd and then Thornton from Anaheim to Ottawa for a 2nd (Anaheim is another affected team at $322,245,164 cap). It makes all those teams just absolutely terrible too cause they can't sign anyone and they trade all their top picks away once they get to their contract year.
