How to unlock the On Lockdown achievement in NCAA Football 10 - Definitive Guide
Just like the past NCAA Football games when this was an achievement for them, u simply can turn off the offsides rule by the pause menu in a game. then u can take a linebacker and sack the qb everytime. or use two controllers and constantly make the second controller lose yards.
Setting the quarter times to a minute also helps. With 1 minute quarters and a good team vs a bad team on freshman this achievement will come rather easily, all you have to do is win the ball once and eat clock.
This one can be tricky. It's not just the offensive yards that count, it's also the kick return yards. I held a team to about 70 yards of offense, but since I blew them out, they had about 50 return yards. If you're shutting them down defensively, then either kick the ball out of bounds every time or chew up the clock with extremely long drives. Obvious mismatches in teams are what will make this easier (USC vs. San Jose State, for example).
If you want, you can also try and get this in a game with 1 minute quarters where it will be much easier to hold the opponent under 100 total yards.
