NCAA Football 11

Start Road to Glory mode using a team in the Independent conference such as Notre Dame, and do well through the season. Since Army, Navy, and Notre Dame are the only teams in the conference, it is the easiest to get into the All-Time leaderboard.

In Road to Glory mode, go to Stats & Records>Leaderboards>Offline Leaderboards>Conference. Here you will see the Legend Rank score that you need to beat for your conference and position. My achievement did not unlock until I reached #10 on the conference leaderboard. Your achievement may unlock sooner or later than that, but as long as you make it onto the conference leaderboard, it will unlock eventually. (Thanks to bogeygolf316 for input on this.)

Long story short, start a new RTG as a RE. Turn offsides off in the house settings and change it to freshmen. Then simply sack the opposing QB by standing next to him before he snaps the ball. Cheevo unlocked in 5 games or less.

This achievement unlocks as soon as you gain enough awards, special plays, passing/rushing yards, TDs, whatever it is that your particular player is being measured on. Therefore, as you progress, this should unlock if you're doing well on the field. End-of-year trophies add a lot of points to your score.

To see the particular score you need to beat, go to Stats & Records, Leaderboards, Offline Leaderboards, Conference. You just have to make it onto the leaderboard, so just beat the lowest score on there.

If you're having trouble with getting a high enough score, you can change the settings. This will disable you from making the online leaderboards, but if you can still get the achievements since those are related to the offline leaderboards.

Go to Road to Glory Setup, House Rules, and click on Modify Settings. Set the difficulty to Freshman. Turn off injuries. Set Player Min Speed Threshold to 0 (so that your fast players will outrun slower opponents more).

RB to Game Rules. Turn off whatever penalties you think are necessary. (I turned off holding so my O-line didn't nerf me.)

RB to Custom AI. Set all User settings to 100 and CPU to 0. This will make you into a superstar.

Now, if you're a QB, set up your audibles so that you can run every play as a long pass play. (I always play QB, so if you're not, do whatever you need to do. I found QB to be the easiest.) At this point, you should score so often that you eventually get benched.

Make sure you save after every game. After the last game of the regular season, make double sure you save. If you don't win the Heisman, and you've been leading, reload that save and resim until you do. The Heisman is worth a lot of points, so you want to make sure to win that. If you're undefeated but don't make the Championship game, and resimming doesn't help, don't worry. You'll probably make it next year. This achievement will probably take two years to get in any case.

Short and simple solution, make a QB, max his stats, and put him on a powerhouse team like Alabama. Make sure he is a starter in the depth chart. Select him in Road to Glory and simulate everything and by the end of the 3rd season you will have all 3 all-time leaderboard achievements. You should need just over 2100 legend score to get this. After 3 seasons I won every game including SEC and BCS, won 2 heismans, and had a total of 2480 legend score.

I believe this is the easiest solution because it requires no playing or really messing with the AI or gameplay and you can get the achievement easily while just simulating. I also got the heisman trophy and QB completion % trophy along the way along with a bunch of awards that also help raise your legend score.

Good luck and please leave positive if this helped you.
