From what I can tell, the contract lengths for coaches are generated when you make the dynasty. The easiest way to do this is to make a new dynasty and pick Army, Navy, Notre Dame, or BYU as your team until you get a 1 year contract for you're coach. Chances are that one of the teams are going to have a coach that needs to re-sign in a year. If not, just restart the dynasty and try again. From there, just follow the directions below.

Since you're an independent team, you can choose who to play against every week. Just set them up against 5 different FCS teams and a few other really bad teams like San Jose State. Then simulate through the season. You should win at least half the games, and you'll be resigned for coach at the end of the season. Takes about 10 minutes and no effort at all.

Let's Do It Again - 20 GS
As a head coach in Dynasty, sign an extension to stay at the same school.

Simple Solution: There is no simple way to actually "boost" this achievement. It's a craps shoot. I started 5 separate dynasties with 5 different teams before figuring some things out.

1. The lengths of contracts change EVERY time you start a new dynasty. One year, Cincinnati had a 1 year contract and I barely got fired by them. I went to try a new dynasty with Cincy again, and their contract was 2 years this time. I don't know why, but it seems that contract lengths are random. I got a 1-year contract with BC and that worked for me in the end. If you find it, I recommend it.
2. If you're trying to boost by simming your season, it's all out of your control. Before your season starts, if you have any rough games that you're able to switch out, then do it and switch in easier opponents.
3. If you're determined to do this by simming, the BEST way to do it is to pick a team that's really really good (Oklahoma, Oregon, Alabama, etc.) and choose to sim through the entirety of your contract. Will it take longer? Yes. But it nearly guarantees that you will be given the option to resign at the end of the year INSTEAD of trying over and over again with different dynasties. For a simple equation, there would be no difference between trying 3 different 1-year contracts and succeeding on your third attempt, and simming 1 3-year contract. The only difference is = At the end of the 3-year contract with the good school, you'll probably be offered the chance to resign.

The other option is to play a legitimate dynasty. If you're trying to do all of the other Dynasty achieves, then that end result is that you're more than likely going to be given that chance to resign.

It takes time, and if you're trying to sim over and over again.... Then it takes a lot of patience.

I was actually the OC and it still unlocked for once I resigned to continue being the OC. Assuming this, it too would work for DC not just as the Head Coach like the achievement says.

Anyway, it's a pretty simple achievement after your contract is up in Dynasty mode the team will asses your goals, pass failed or what. If they feel you've done enough to stay, right before the coaching carousel begins you'll have the option to sign with your team.

I play as boise state for 2 years i went to the national champions each year and got resign with them and the achievement should unlock right after
