Best case: 9-3 (6-3)
The Sun Devils are almost always a really hard team to predict the past 10-15 years, they underwhelm when they are expected to be good and overwhelm when expectations are low. I think most expect the Sun Devils to win six or seven games, but I could easily see this being a season where they sneak up and overachieve. Todd Graham's system relies a lot on momentum and they have the personnel and comfortable schedule to make another surprise run.
Manny Wilkins could end up being a more-dangerous playmaker at quarterback than Mike Bercovici and Demario Richard and Kalen Ballage could be a punishing running back duo which is the best in the conference. Graham's defense has a lot of experience and could have a bounceback season and attack Pac-12 backfields after a season where it seemed like every blitz backfired. They're due, okay?
The Sun Devils' schedule sets up nicely. They could easily only lose one home game - lets' say they lose one in the pack of Arizona, UCLA, Utah and Washington State. The road could be tougher with Oregon, USC and Washington on the road, but let's say they grab a win in one of those, lost just one at home and they get to 9-3.
Worst case: 5-7 (3-6)
The Sun Devils were a wreck towards the end of last season and Graham's signature defense regularly got bombed throughout 2015. There isn't much to suggest the Sun Devils won't carry this into 2016.
They have too much talent, experience and proven coaching prowess from Graham to bottom out in my opinion, but they could miss a bowl, winning just their two gimme non-conference games and grabbing just a few in-conference wins.
