Every team has its turning points during the season. But the Missouri Tigers faced more than their share of adversity in 2015.

Perhaps it will make them a stronger football team down the road, but for now, the adversity resulted in Missouri finishing with a losing record. The Tigers turned down a rare bowl berth for a 5-7 team, missing the postseason for just the second time in the last 11 years.

Here are the five most significant moments of the 2015 Missouri Tigers season:

5. Harold Brantley accident: The junior defensive tackle was the heart and soul of the Tigers defense until a car accident in June. Brantley suffered a broken tibia, fractured ribs and knee ligament damage in the accident.

Although the Tigers ultimately had underclassmen step up and play well on the defensive line, this was a huge blow before the season even started.

4. Maty Mauk suspension: Junior quarterback Maty Mauk played four games, but the program suspended him after the first conference game for violating unspecified team rules. Mauk was involved in an off-campus incident four days prior to his suspension.

Freshman quarterback Drew Lock was fine against South Carolina in his first start, but his inexperience hurt Missouri the rest of the season. In the final seven games, Lock had one touchdown and seven interceptions.

3. Loss to Florida: Lock had two of those picks against Florida the week after the South Carolina victory. The Gators crushed the Tigers, 21-3. The game turned out to foreshadow the changing of the guard in the SEC East.

2. Players’ strike: In early November, the Tigers and the University of Missouri made national headlines. A group of black players on the Tigers roster announced they would stop participating in all football activities until university system president Tim Wolfe resigned.

At that point, the season was pretty much lost, but at least the Tigers were united. Coach Gary Pinkel supported his players. Wolfe resigned on Nov. 9.

1. Gary Pinkel announces retirement: Less than a week after the threatened strike, Pinkel announced that he would retire at the end of the season due to health reasons. He was diagnosed with lymphoma in May of 2015. Pinkel’s retirement was the final blow of a very tumultuous season.

Missouri will try to pick up the pieces next year with new head coach Barry Odom.
