I have somehow topped my fail from last night, as myself and 2 others gave the third-worst answer to this question.
In 2015, this WR suffered a kidney injury in Week 8 (on a TD catch, no less), and was lost for the season.
In 2016, he didn't even finish the first game, not even the first half. He tore his right ACL was done for the year.
Rawlz517 can verify that my answer to Question 19 was San Diego WR
Keenan Allen.
