I picked Oklahoma, played every game, and did all recruiting manual. DO NOT accept the contract extension at the end of the year. The other achievements were popping, like Hometown Hero and Best Class ever, but not Dual Threat, until I reloaded the save, didn't do the contract extension, simmed the offseason recruiting (I was already number 1) and the achievement popped on signing day. I ended up with seven 5 stars and nine 4 star recruits. Hope this helps.
