The Jacksonville Jaguars drafted defensive end/outside linebacker Dante Fowler third overall. Fowler was arguably the top defensive prospect and perhaps, on some boards, the top overall prospect.
Fowler was injury-free during his college career at Florida. Unfortunately, Fowler tore his ACL at his first practice with the Jaguars. He will miss the entirety of the upcoming season.
Denver Broncos tight end Jeff Heuerman, a 2015 third round pick, tore his ACL and will be sidelined all season. Baltimore Ravens undrafted rookie cornerback Julian Wilson broke his leg, and Houston Texans DE James Rouse tore his Achilles at rookie minicamp.
Draft prospects prepare for their Pro Days, and, if they’re invited, the Scouting Combine. The time between the draft and the end of college practice (typically from December to early January) isn’t usually devoted to football training, which can cause injury.
Injuries occur in football, but the NFL could try to minimize this by moving the draft back to April and shortening the time between the end of college practice and NFL offseason training.
