Overpowered:
Army
Georgia Tech
Navy
(Triple Option teams in general)
Underpowered:
Oklahoma
LSU
The way I fixed this in my dynasty is to edit coaches' playbooks. I completely got rid of triple option playbooks because every team that ran triple option was consistently winning 10+ games every year. Oklahoma always did poorly under Bob Stoops with the standard Oklahoma playbook for some reason, so I changed it to a different multiple-style playbook. I did a similar thing with Les Miles after I saw LSU go 9-17 in two years.
Please suggest other teams that are over/underpowered in your guys' dynasties or refute the ones that I've nominated.
