There is a post on LR about NAU's training, read it (training spread sheet can be found in a link).
Agree with comments that most college coaches do not know what they are doing.
OP, misunderstanding might be intensity. Don't go to the well with training intensity all the time (end of the season either). If you follow your coaches plan, get some hills in on those runs (most of them), just get up them, you'll feel stronger on them week by week, but maybe put more intensity into one or two of them each week, no need to hammer them everyday. You could also do one of the 'strides' sessions up a short hill.
Recovery days matter too. You can get in 'base mileage' (whatever that is ... usually long slow distance), if done easy as RECOVERY (pace may vary), and do intervals on other days, which are what hills simulate, particularly if one one of those days you run the hills a bit faster. Get on some trails too.
