Texas endured another roller-coaster season with unbelievable highs -- upset wins against Oklahoma and Baylor -- and a whole lot of difficult lows on their way to a 5-7 record that meant no bowl game for just the third time in the last 22 years.

Let’s take a closer look at Charlie Strong's second season in Austin with Texas' season report card:

Offense: D+

Trusting Shawn Watson and Joe Wickline to deliver an uptempo spread offense in 2015 was a disastrous move for Strong, and having to demote the co-offensive coordinators after one game forced Texas to play catch-up all season long. Jay Norvell did an admirable job of trying to forge a run-first identity around quarterbacks Jerrod Heard and Tyrone Swoopes. The Horns developed some young talent along the way -- D'Onta Foreman, Connor Williams, Patrick Vahe, John Burt -- but the results weren’t pretty or consistent. Texas scored 25 points per game in Big 12 play and finished ninth in the league in points per drive (1.8).

Defense: C+

The defense didn’t meet expectations, but the truth is 2015 was a rebuilding year for that unit. Malik Jefferson earned Big 12 Defensive Freshman of the Year honors and led a group of freshmen who ended up playing a ton of snaps. The youth movement makes for a promising future -- those rookies played a big role in Texas’ upset of Baylor -- but also present-day unpredictability. Texas had some nice pieces, but its issues started up front with a defensive line that never emerged as a strength.

Special Teams: C

Maybe a harsher grade is suitable here, since the special-teams gaffes against Cal and Oklahoma State might have been the difference between 5-7 and 7-5. But all in all, the Horns were generally average in the game’s third phase this season. Nobody booted more punts in the Big 12 than Michael Dickson, and the Aussie import had a solid if up-and-down freshman year. Nick Rose improved as a senior, hitting 13 of 17 field goal tries, and Daje Johnson had one punt return TD.

Coaching: C

Texas’ upset of eventual Big 12 champ Oklahoma was a masterpiece of coaching and motivation. Hard not to look back on that game, though, and recognize it was a sign that Texas had enough talent and potential to make more progress in Strong’s second year and win seven or eight games. In blowout road losses at Notre Dame (38-3), TCU (50-7) and Iowa State (24-0), Texas’ staff got outcoached and its players looked unprepared. Stability and continuity have proved elusive so far but are badly needed.

Overall: C-

The standard at Texas is Big 12 and national championships, and Strong has never shied from saying that. At the end of his first season, he said Texas would never lose six games again under his watch. His second season was a disappointing step in the wrong direction. The long-term plan at quarterback remains a question mark, and another offensive makeover is coming. The freshman class is exciting and offers meaningful hope, but Texas still has a long way to go to play for the conference crown and 2015 was a rough reminder of that reality.
