You need an 81 or less OVR team... with no more than 10 gold cards and no silver cards. And you'll need to pick up 6 UK players when they drop... so just get the cheapest ones and toss them in as backups.
But I think the key is to go pick up a low gold kicker or punter and sub them in for your QB1 (move your real QB1 to your QB2 slot and then sub him back in during the game). That alone will take your team OVR down considerably and you only have to swap one player.
If you need to tank a bit further... pick up a low gold FB and put him in as your HB1... and put your real HB1 into one of the specialist slots and then just sub him back in during the game.
Unless EA changes things, you don't have to go out and pick up a bunch of low OVR cards.
