Russell Wilson improves in the second half of the season. But the details of his improvement may be surprising.
In his Seahawks midseason awards, Danny Kelly made an encouraging observation:
Wilson's second half splits have by-and-large been better than
his first halves, with completion percentage, yards per attempt,
and rating improving every year after the halfway point
That's good as far as it goes, but those statistical numbers are not independent (more completions causes higher yards/attempt and a higher passer rating) and they don't account for rushing or sacks. So I put together some more aggregate performance measures.
