FEBRUARY 2023 UPDATE: The servers for this game are now closed, making this achievement forever discontinued. I'm leaving the solution up in case EA brings back the Draft with their new football franchise.
BOOSTING SOLUTION FOR ONE PERSON DOUBLE BOXING.
(Obviously this can be modified to add other gamers, but this is by far the fastest and quickest way for one person to get this achievement by themselves as long as they have two Xboxes.)
Servers for this game close February 14, 2023. I am providing this solution for everyone looking to get this done ASAP.
This will require 2 Xboxes and 8 Xbox Live accounts, including the account that needs the achievement. The main account will need Xbox Gold status to play online. With this account, set one Xbox to your Home Xbox and then play on the other one. This will give the ability for any dummy account playing on the Home Xbox to play online without needing to buy additional gold accounts.
Create an additional 3 accounts on the non-Home Xbox to go along with your main one. Number them, the main account will be 1 and the rest will be 2-4.
On the Home Xbox create 4 accounts and number them 5-8. All the accounts will have to go through the tutorial screens during the process of setting up a FUT team for them.
That's the easy part, now the hardest part of the achievement: each account will need a massive amount of FIFA coins to buy an entry into the FUT Draft. Each entry costs 15,000 coins and you will need a LOT:
1 - 15,000
2 - 30,000
3 - 30,00p
4 - 45,000
5 - 15,000
6 - 30,000
7 - 45,000
8 - 30,000
That's a grand total of 240,000 coins needed. The different in amounts are because some of the accounts will need to re-enter the Draft after losing. I haven't found an easy way to get coins, hopefully you've been playing this game for a long time and have a bunch saved up or know someone that can buy an inflated card off you for a lot of coins.
I will say there's an alternative to this, you can use real money to buy FIFA Points, which work in lieu of coins. The in-game points store is closed, but you can still buy FIFA Points cards off Amazon, at least in the United States. I do not condone this method, I am JUST mentioning it as an alternative to a very long coin grind. If you do go that route, these are the amounts of points you would need:
1 - 300
2 - 600
3 - 600
4 - 900
5 - 300
6 - 600
7 - 900
8 - 600
Sadly, Amazon does not let you choose your amounts but only sell cards in increments of $15 and up, making this a very expensive way to get the achievement.
Regardless, once you have 240,000 coins divvy them up among the accounts as shown by selling cards back and forth for the amounts indicated and enter the Online Draft with each account. It doesn't matter who you get, we won't be playing games.
Rather, when you match up with one of the dummies the loser will score THREE own goals (i.e. passing the ball ball to his own goalie and running into the net). Once the loser has scored against himself three times, he can forfeit the match. This will give the winner an official win. You can do this the entire time, even in the Final for the fourth win. This will save a ton of time as well as avoid possible server crashes, because this game is not super reliable.
With all that out of the way, follow this path in the EXACT order listed. This must be done because accounts CANNOT play each other again in the Draft, and this order ensures they will not.
1 v 8, 1 wins. 8 will re-enter the Draft
4 v 7, 4 wins. 7 will re-enter the Draft
2 v 7, 7 wins. 2 will re-enter the Draft
3 v 6, 6 wins. 3 will re-enter the Draft
1 v 7, 1 wins. 7 will re-enter the Draft
4 v 6, 6 wins. 4 will re-enter the Draft
1 v 6, 1 wins. 6 will re-enter the Draft
4 v 5, 5 wins. 4 will re-enter the Draft
3 v 7, 3 wins. 7 is done
4 v 8, 8 wins. 4 is done
2 v 6, 2 wins. 6 is done
3 v 5, 5 wins. 3 is done
2 v 8, 2 wins. 8 is done
2 v 5, 5 wins. 2 is done
1 v 5, 1 wins and unlocks the achievement!
