You're right about Koz, John. He's definitely more on the H-back track than the blocking TE role. In fact, if you read Nunyo Demasio's chat transcipt (
http://discuss.washingtonpost.com/wp...asio060704.htm ), he seems to feel that Koz could be the starting H-back, instead of Sellers or Cooley. His experience definitely gives him an edge going into training camp, but I'm not sold on his athleticism. Sellers and Cooley bring a combination of size, versatility and athleticism to the role that could make the H-back position a very special weapon in this offense.
As far as the wideouts, I could definitely see Gardner losing his #2 job by mid-season, if not by the end of the preseason. McCants is definitely going to see more playing time, and I think Gibbs would like to see him develop into a reliable possession receiver and red zone threat. But that's not a given. Much like Gardner, he has the physical tools, but his focus and determination have been suspect at times. McCants also sat out much of the offseason work with a shoulder injury. Thrash and Jacobs bring the focus and work ethic that Gibbs adores, so they represent significant wildcards in that respect; plus Thrash has tremendous experience, and Jacobs has loads of potential.
One thing's for sure: the logjam at wide receiver presents Gibbs with a conundrum that a lot of coaches would love to have.
