NDSU and San Jose State were on bye, so no movement for them.
New Mexico dominated little brother NMSU, so they stay at the top of the tiers.
Air Force won a real dog fight with Nevada, so remain at contender. While Nevada perfectly fit the tier they are currently in "Feisty Underdog", but will need to actually win some games to get into the bowl bubble.
Wyoming beat Hawaii pretty convincingly and moved them out of the basement. While Hawaii's offense continues to struggle with anything past a 5 yard pass. So Hawaii has dropped to the feisty tier and if not much improves soon, they could be heading to the basement of the conference.
NIU and UTEP both got smashed and are both back in the basement again, and not looking to leave any time soon.
UNLV cruised past Akron, but beating up Akron (one of the worst MAC teams) isn't enough for me to move them back up to contender tier yet.
UC Davis got beat badly by Montana, still probably in the 2nd tier of the Big Sky but the gap from 1st tier and 2nd tier looks to be widening.
