What one thing makes you nauseated, your head hurt and makes you shake your head and doubt we are still going right direction? Salary cap? LT/QB/Barwin contracts up after 2012? Not convinced players like KJ, JJ, Walter, Shaub, Andre Johnson are playing up to contract or your concerned about health? Your still not certain Gary Kubiak is right head coach? What is that ONE thing that makes you go GRR!
