Thought this might be a good place to dump this given the talk about kickers over the last week.

Through four weeks, NFL kickers have connected on 285 of 303 kicks, good for 94.1% accuracy. This number is slightly higher than the predicted 92.7% for one reason: NFL kickers have the choice of where they place the ball between the hashes on extra points. Field goals are required to be placed on the hashes if the previous play ended outside the hash marks, or where the play ended if it occurred inside the hash marks. Extra points allow the choice of kicking angle. Kickers will naturally select a location on the field they feel most comfortable, resulting in a slight uptick in accuracy.
Broadcasters, fans, and journalists have noted that the increased accuracy has coincided with the majority of games being played in good weather. The assumption is that it may be more difficult to make XPs from the longer distance during the colder part of the schedule in November and December. A casual glance at the data might even seem to confirm it. However, this is not borne out by the historical data.
