Nwachukwu was stuck in a numbers game with the Texans. They brought in four receivers this offseason -- two in the draft and two in free agency -- and had a decision to make about whether they would keep five or six receivers.
The landscape of the Texans' receiving group is still a bit murky. There were five players who I considered locks -- DeAndre Hopkins, Nate Washington, Cecil Shorts, Jaelen Strong and Keith Mumphery. If they keep a sixth it will be Keshawn Martin, but we don't know Martin's fate yet.
Next week's episode of "Hard Knocks" will likely feature Nwachukwu's release. They've so far shown him charmingly peppering an astronaut with questions during a visit to NASA, telling Hopkins he'd delete his number if he got a yorkie in a manbag, and fishing with former college and pro teammate Travis Labhart.
