Madden NFL 08

ok this one is easier that it looks, just throw a screen pass(i say screen because you have a better chance of completing the pass when the other player is close) to the "B" player 10 times in a row

The achievement is simple and clearly explained, but some players may experience some problems caused by the last patch.
The technique to complete the achievement is as follows:
- start a new Play Now match, User vs Cpu, and select Colts for you and Texans for Cpu. Set 5 min. for time e Rookie for difficulty level.
- Pause the game and take to the max the % all of user option under the AI configuration. At the same time, set to 0 all the options of CPU and disable fatigue and injuries.
- when you are in offense, select the first play under the tab TE of the "by player" set. In this play you can see the the player marked with the A button that moving perpendicular to the field from right to left.
- hike the ball, wait a moment for the movement of the player A, and make the passage.
- when you catch tha ball, go offside and repeat 10 times (remember to make a 1st down before every 4th attempt) and supersim to the end of match.
The achievement will unlock after the end.

Some times, the method just described might not work, especially if you downloaded the patch. In this case, remove the game if installed, and start the maintenance of the HD by deleting the disk cache (it's on option of the memory section of the dashboard). Obviously, once you start again the game, refuse to download the patch and play it disconnected from Xbox LIVE. After that, repeat all the operation listed above.

The same method can also be used for 20 Completions in a Row.

Should be 10 plays in a row, all on the same drive. A streak can span across quarters, but the streak seems to end when you score, kick or run any play other than a pass play...

As mentioned above, "Dual TE Flat" is never defended against...

Max out your running backs receiving stats, then do a screen pass to him ten times. He won't drop it. Do not throw it to any other player besides your running back until he has ten without dropping any!
