Derrell Johnson-Koulianos, for those who don’t remember, was a star wide receiver for the Iowa Hawkeyes from 2007-2010, and still owns the records for most receiving yards and career receptions in school history. But DJK, as he was/is known, was arrested and charged with numerous drug-related crimes in December of his senior season, leading to a suspension for his team’s bowl game. While the result of the arrest eventually became a simple marijuana possession guilty plea, DJK was never able to find work in the NFL, despite having the physical talents necessary.

Many have theorized that his former coach, Kirk Ferentz, may have “blackballed” him from the NFL due to a strained relationship between the two. Whether or not it’s true, the former wide receiver is soon going to release a tell-all book that, we’re guessing, is going to be a scathing account of what he claims goes on behinds closed doors at Iowa. Ahead of its release, DJK went OFF today on Twitter.

This is just a portion of what he said. For reference, KF = Kirk Ferentz.

Would u like it if u slaved for someone 4 5 yrs then when you arrived @ adversity they abandon you & tell potential employers not 2 hire u? — DJK (@coachkoul) December 17, 2013

At least 10 NFL teams said to me “We understand you made a mistake but my concern is no one at Iowa had anything good to say about you.” — DJK (@coachkoul) December 17, 2013

Recruits need to consider this about KF before going to Iowa. It’s all good when you’re converting 3rd downs and touchdowns but don’t F up. — DJK (@coachkoul) December 17, 2013

Got involved in that bad stuff because I followed 2 leaders on the team who encouraged me to try it. Two guys the coaches chose as “leaders” — DJK (@coachkoul) December 17, 2013

There’s so much shit that hasn’t been revealed about what goes on and I experienced. This book gonna open some eyes. — DJK (@coachkoul) December 17, 2013

Not blaming anybody. I take ownership for how it went down 100%. But it’s only fair people know all the truth. — DJK (@coachkoul) December 17, 2013

College was crazy. Never expected that from Iowa. I’m physically and mentally stronger than ever. Good things are ahead. — DJK (@coachkoul) December 17, 2013

Not bitter about not being in the league. I lost the passion to play after arrest. Which is why AFL/CFL didn’t work out. I wasn’t hungry. — DJK (@coachkoul) December 17, 2013

My issue is I’m a good person and they tried to demonize my character. Being a good person and Coaching is my now my passion. — DJK (@coachkoul) December 17, 2013

I want to impact young aspiring athletes. I have the knowledge and a great story to tell. — DJK (@coachkoul) December 17, 2013

I knew after my first conversation with KF at Iowa it wasn’t. Going to be a good relationship. — DJK (@coachkoul) December 17, 2013

“Your names Derrell not DJK. And you’re not bigger than the program.” I was like WTF? Okay. — DJK (@coachkoul) December 17, 2013

No1 likes me talking about this now but a big book offer came. Plus every day a question about “what happened?” gets asked. — DJK (@coachkoul) December 17, 2013

People want me to move on. I am once for all. Right after this publication. — DJK (@coachkoul) December 17, 2013

The money, the drugs the dictatorship of a program. All of it will be in the book. — DJK (@coachkoul) December 17, 2013

FYI: TWO HAWKEYES ENCOURAGED THE BOOK THIS WEEK. One currently in the league one currently on the team. What does that tell you? — DJK (@coachkoul) December 17, 2013

Peeps will hate me either way. I’m going thru w| it and I’m not afraid to show my vulnerability. Love me or hate me. When it drops, read it. — DJK (@coachkoul) December 17, 2013

It’s not about money. I don’t need it. Trust me. — DJK (@coachkoul) December 17, 2013

Actually I encourage all students to go to Iowa. Hellava party school. Screwed up my morals. Student-Athletes should not attend IA under KF. — DJK (@coachkoul) December 17, 2013

Coaches/GA’s that came in at my time at Iowa would say to me: “They think you’re bad, they should see the kids I just got done dealing with” — DJK (@coachkoul) December 17, 2013

Those coaches will be named and quoted in the book. — DJK (@coachkoul) December 17, 2013

Book will be in Iowa and Ohio book stores mid summer 2014. — DJK (@coachkoul) December 17, 2013

Let me be clear. This is not about the U of Iowa or the NFL. This about KF demonizing my character. whose son got arrested TWICE. — DJK (@coachkoul) December 17, 2013

KF’s sons James Ferentz asked me to buy him boos when he was too young livin in hillcrest dorms. — DJK (@coachkoul) December 17, 2013

Like I said. This book gonna open some eyes. I should of had better judgment but I certainly didn’t have the people in charge on my side. — DJK (@coachkoul) December 17, 2013

KF told my parents two weeks b4 arrest after OSU ’10 “Tell Derrell I have one more thing in my pocket for him.” My confused parents told me — DJK (@coachkoul) December 17, 2013

Two months ago I get an anonymous letter from someone who says KF worked with the ICPD on getting a “bust” — DJK (@coachkoul) December 17, 2013

KF punished me by making me wear a trash can on my head for an entire practice while recruits parents were at practice… — DJK (@coachkoul) December 17, 2013

…then Chris Doyle took a picture and hung it in the weight room. You think recruits will like that? — DJK (@coachkoul) December 17, 2013

If you don’t believe me ask my teammates who are on twitter. I have no reason to lie. — DJK (@coachkoul) December 17, 2013

Put me in a room anytime anywhere w| KF and let’s him deny anything I have to say. Sum1 make it happen. His recruits will hear about it all. — DJK (@coachkoul) December 17, 2013

I’ve been advised not to reveal any more details about my experience under KF. Look for the book on shelves this summer. — DJK (@coachkoul) December 17, 2013

KF was so pissed I was on the cover SI. He was seeing red. He expressed that to the team after a practice in the nices way possible. Lol. — DJK (@coachkoul) December 17, 2013

This should be an interesting book, to say the least.
