I keep seeing people say things like this, about the stability and/or reliability of Graham, I don't get it. If Hartley taught us anything its that the past success of a kicker is irrelevant. Last year Shayne Graham made 4 short field goals and missed 2 field goals. (Why he missed is debatable, but a miss is a miss) And so far this year he has missed at least 3 reported field goals in practice, one 33yrd extra point try, and now appears to be injured. Don't see how he's the "safe" option.
I don't know if Dimke is the answer, but I know I don't want Graham as my kicker.
