Looking around FBS and FCS there aren't a lot of guys that fit the criteria that I would like in an Offensive coordinator. Here is the criteria that I believe we should be looking for:
1. Someone who has been successful
2. Someone who has been an offensive coordinator for 3+ years
3. Someone who is familiar with BYU recruiting areas - Western USA and Texas
4. BYU would be a step up for them - so it would be reasonable they could take the job.

Criteria #2 kicked out a lot of guys. There are a lot of young up and coming Offensive Coordinators in the Western States. But one and two years is not large enough sample size for me.

Here are the only two names that I came up with -

Tanner Engstrand University of San Diego- http://www.usdtoreros.com/sports/m-footbl/mtt/tanner_engstrand_291132.html

Kalen Deboer - Fresno State - http://www.gobulldogs.com/coaches.aspx?rc=743&path=football
