I think most in all likelihood feel this way but for the reason jwins mentioned, I think one loss could happen early on. Everyone is overlooking Northwestern...they are returning some real talent and we are away at night early in the season...could spell a loss.
As for us: I will give a full report later on in the summer but I feel where we could see the biggest drop-off is our front 4...Simon, Hank, Goebel, and Williams will not be easily replaced. I think we will be very good on the edges but Hank/Goebel really got the job done inside...Bennett can be a star but is always hurt and Hale is far from proven. Schutt will have to be a full time player for us now but has the talent. Any of Bosa/Price/Hill could come in and have an impact right away. I think this defense can still be very good but our DL just can't be a huge dropoff from last year...there will be some dropoff, it just can't be drastic.
Shazier is a stud and someone will step up (my guess is Perry, maybe Grant) and we will usually only have 2 LBs on the field at once anyways. Our secondary will be strength for us on defense and will only be better by adding Bell and with Powell's emergence.
On offense, I think we are going to be off the charts honestly. I think the talent is there but above all, the system is in year two and will really resonate with our guys. I think D. Smith will become more consistent and Philly will build off his breakout year. Thomas is ready to go now at WR and our TEs have rave reviews from UFM. Fields had a phenomenal spring and Spencer is serviceable. We already know Hyde is a stud and Rod was starting to breakout, but then Ball and Dunn looked great this spring as well. The returning 4 are the best unit as a whole imo (I don't say that lightly) and Decker was THIS close to starting over Fragel...I think this whole "competition" at RT is simply UFM trying to maximize Decker's talents...our OL is going to be the strength of this entire team and Decker has a few games to get settled in before any real competition. Braxton has noticeably improved his mechanics and looked sharp in the spring game. All this being said, I think Wilson and Marshall are going to provide a spark in the open field that makes this offense truly potent...I wouldn't rule out Corey Smith turning heads either.
Now of course I always have some glowing post like this at the beginning of the year. But I am realistic and I know there will be adversity and the leadership will need to step it up...and that is the huge question mark. In sum, anything worse than a Big Ten title and a win over scUM would be a bust. However, if we achieved that with one loss along the way, I would not be disappointed, even with our patsy schedule. Of course a NC is always the goal but I would find no way that a BCS bowl appearance and an 11 win season would disappoint me at the end of the year.
