I mean, literally any player you draft could tear an ACL in practice tomorrow and be out for the season. That's fantasy football. Every player carries risk. Sure, some carry a bit more than others, but at this point I don't consider Allen to be one of them. And I don't think he's with the elite group of receivers more because he's never performed like one. He's a low-end WR1, high-end WR2 guy. A guy who averages less than 15PPG (.5 PPR), not a stud like Hopkins or Julio that can get up in the 17-20 PPG range every year.
All I know is that I'm not taking Allen until at least the third round and it has absolutely nothing to do with me being concerned about his injury risk. It's just the reality of his expected production.
