Madden NFL 17

This achievement can be done quite easily using the Bronze Player Trade-In MUT set;

From the main menu, go to ultimate team and once you are in, scroll all the way to the right to find Items. Under items, you will see sets. Click on it and select Earn Badges. Once that is done, scroll down to Bronze Player Trade-In. To complete this set, all you need to do is find 9 bronze players (as of 2/19/17 you only need 5 bronze players. Thanks Rordor for the info) from your available items and put them in. Once 5 bronze players are put in, you will get the achievement and a bronze pack.

This achievement is pretty simple, but you may need to play a few games or challenges to get more players or coins to buy more players if you don't have enough bronze players to put in. If you have any questions, leave a comment and don't just downvote.
