Moving the
TL;DR to the top:
(1) Get two controllers.
(2) Download a 99 overall roster and use that for both teams.
(3) All-Madden difficulty, 15 minute quarters, no accelerated clock.
(4) Primary controller on defense: FG Block.
(5) Secondary controller on offense: Shotgun, Quick Slants
(6) Primary controller controls MLB. Move him back and over a few yards, toward the WR.
(7) Secondary controller throws to outside WR.
(8) Primary controller attempts tackle, hopefully wins battle.
(9) Lather, rinse, repeat.
Full SolutionConsidering 32% of players have this achievement, it's maddeningly (no pun intended) difficult to get if you're actively trying for it. M-Easy's solution below worked well for me, and I was able to get it in ~15 minutes.
You're going to need two controllers. Download the BILLZ99 roster (or any other roster you can find where every player is a 99 ... most likely the one you used to get the legacy achievements), and have both of your controllers play as that team against each other.
All-Madden difficulty, 15 minute quarters, no accelerated clock.
Your primary controller/account will be on defense. Choose any Field Goal Block play, and control the MLB (the guy NOT on the line of scrimmage), and move him back about 10 yards and 5 yards to the left.
Your secondary controller/account will be on offense. Go into Shotgun formation, and call Quick Slants. Snap the ball, wait about half a second (for the WR to actually start his slant), then throw a bullet pass (hold down the button) to the WR on the most left side of the screen (in my case, it was the
receiver).
As soon as you throw the pass with your secondary controller, use your primary controller to line up and try to tackle the player. You won't get a tackle battle every time, but I got one per minute of game-time (I unlocked after 6 tries with 9 minutes to play in the first quarter).
When the tackle battle starts, repeatedly mash the button that shows above your player's head; if you make the tackle, that's a "win." If the WR breaks free, you lost, and it doesn't count.
After each play, hold down
on the secondary controller to hurry up and call the same play again without having to go to the play select screen. More attempts in less time!
If your primary account causes a turnover or your secondary account scores, just punt the ball back to your secondary controller and get back on defense.
The achievement will pop as soon as you've won your third battle; no need to wait until the end of the game.
