I am confident that Kevin Boothe will correct the issue as he gains more experience. Otherwise, his play has been very good; both his run and pass blocking. As for David Baas, I wouldn't count on him for the future. Those headaches aren't migraines as much as the symptoms are similar. They are related to a neck problem which has him and the team more than a little concerned.
It really is too bad that Koets was lost to a torn knee ligament, herniated disk. I think he might have paid dividends much as we hope Boothe will. Issues of health and durability seem to be taking over the game.
Cheers!
