On this particular point the author displays complete ignorance about the kicking in football. Distance is ALWAYS the issue on a long field goal attempt -- even if the kicker has gotten plenty of distance on the kick and missed wide to either side. The goalposts appear closer together from a longer distance, and even a kicker who is capable of hitting a 60-yard field goal will use different mechanics for a 50-yard attempt than for a 30-yard attempt.
So, did the kicker's accuracy suffer because he used the wrong mechanics for these two attempts? Because in both cases the kick was long enough. Now if you are suggesting that the reason he missed is because his teammates didn't get him closer for the attempt, then you are correctly placing the blame for the two missed kicks on the Seahawks.
