what is the best way to get more coins faster?

ive been playing madden for years now and i love the new ultimate team addition to the game.... my only problem with it is that everytime i get coins i have to spend them because more players contracts are expiring i have a decent team at a 90 or so but i cant seem to stock any coins because everytime i get done with a game i have three players being out any advice?

put off playing games for a while and sit in auctions to turn profit without sacrificing players you want. buy packs and sell them for profit look at uniforms there usually really easy to sell for big money. once you get bank contract up who you want to keep for a while once you have your team set then start playing again so you can feel comfortable.
