Jahvid Best is a RB for the Detroit Lions
Set the skill level to ROOKIE with all the Player Sliders up to 100, and the CPU sliders down to 0. Put it on 1min QRTS with no Accelerated Clock.)
((Go into the Depth chart and move Jahvid Best to 2nd string HB, then go to WR and place him as your 1st or 2nd string WR.))
on the first play, scramble all the way back to the 1 yard line, and run out of bounds (Be careful not to get a SAFETY on yourself.) Pick a play like FOUR VERTICALS, make sure you have BEST on a fly route. (It helps if you put receiver closest to your O-Line on a blocking assignment using HOT ROUTES.) This will give you a little extra security.
Simply Air the ball out to BEST, and take off. You need to do this twice to have enough yards (From your own 1 yard line.)
This Achievement won't pop until after the game is over, and YOU CANNOT SUPERSIM, you must finish the game.
I did this on 1 minute quarters with the COWBOYS Playbook, and i just kept bombing to BEST all game long, I had 443 yards receiving with him at the end.
NOTE: If you have trouble beating the coverage for some reason, use another controller, and choose FG BLOCK for the defense. Just be quick to Air out your pass, and this will assure that BEST (or any of your receivers) are NOT covered.
