Correct, according to this. DJK contacted Howe complaining about not getting a shot at an NFL camp.

You guys have had a good history, successful history of guys that come through your program and get into NFL training camps even if they’re not drafted. Are you surprised that Derrell never got into a camp this off season?
COACH FERENTZ: I mean, when it comes to who the NFL, what they see and what they choose to do, I don’t know if I’d ever be surprised. They all do their homework, and it’s in their hands.
He reached out to me and said that he thinks that you maybe have said some negative things about him that’s kept him out. Can you comment on that?
COACH FERENTZ: Yeah, first of all, I really don’t want to go into a dissertation with someone that didn’t finish the season, other than to say, typically players’ actions speak for themselves, and I haven’t slammed any player to anybody since I’ve been here. That would be a no, I guess, right? Was there a question there or not?
Did NFL people contact you about him and ask you about his character?
COACH FERENTZ: No. I have not had one question since I had very few questions in the fall quite frankly. So on that topic I can unequivocally say nobody has asked me anything since and including December. Hawkeye Nation has been waiting to hear the answer to that one, right? That’s like yesterday’s news to me, right? Just to answer the question, no.
You had 75 of 82 from your media guide from 2002 to 2009 that got into camps. It seems a little puzzling that a guy that is Iowa’s all time leading receiver couldn’t find his way into a camp.
COACH FERENTZ: Again, I’ll go back, I haven’t said anything negative about anybody, period. And the other thing I’d just add, I imagine most of the guys that ended up in NFL camps probably played in their last game as a senior on the team. That would be my guess. I’m just guessing. I don’t know, I’d have to go back and research that.
