I am not going to vote until the end of the season.
However, the numbers are not so good.
In 2014, our first full year in FBS, we went 6-6 against a schedule that included two P5 programs, a Marshall team that was every bit P5, and a win over conference champion Rice.
NCAA Strength of Schedule was 107

Nationally, out of 128 FBS programs, we were 51st in scoring - 401 points total @ 33.5 points per game and 56th in total yards - 5303

2015 was our first losing season. We went 5-7 with a schedule that was easier and included only one P5.
Our NCAA Strength of Schedule was 109

Nationally, out of 128 teams, we dropped
substantially in offensive output.
We were 101st in scoring - 291 points total @ 24.3 points per game and we were 99th in total yards - 4455

2015 was a year that many thought we would improve overall, even without Heinicke.
Our offensive output dropped dramatically. Our scoring went from one place away from top 50 to below 100; and just as drastic a drop in total yardage gained.
Our coaches may or may not feel the heat after this season if we don't improve, but they certainly will if we continue a downward trend.
EDIT: By contrast, the defense improved - up about ten places in both total yards allowed and points allowed.
