If I am not mistaken, Kerney has been prone to injury.
kmac, I haven't heard anything either in terms of the coaching staff saying they'd want to, or have even considered, releasing KGB.
However, I think TT and MM teling Ferggy he was still in their plans, and not doing anything with KGb, might be an indication KGB's job isn't so secure.
Otherwise, I think it's more an issue of people wanting KGB to be gone, and some idiot news writers (specifically at the Press Gazette) flaming their limited football knowledge as if they know what's going to go down and suggesting KGB being released is a sure thing that has led people to FALSELY conclude KGB is a lock to get the ax.
I still think by the time it is all said and done, KGB's salary may be a good price for a specialist pass rusher. In the end, we may end up paying around 8-9 million to Jenkins and KGB to serve as a run specialist and pass rusher, which may be just as wise as paying one DE, Kerney/Smith/Thomas the same price to come in be good in the pass rushing are and at least average in the run stopping area.
