Kirk Cousins Throws a Very Catchable Ball

3. Kirk Cousins is Deadly Accurate
One thing that you might've noticed in the previous table is his 69.8% completion rate in 2015 ranks 11th in NFL history for a single season.  It was the second best completion percentage ever by a Washington passer behind only Sammy Baugh's 70.3% in 1945. http://www.hogshaven.com/2017/2/17/14635736/skins-stats-ten-reasons-kirk-cousins-is-worth-the-money

The reason for this is in good part that Cousins throws a very catchable ball. Contrast him with the QB of the Carolina Panthers, who throws blue darters. All we ever hear is that these great receivers are making Cousins better. I would accept that in the case of Reed. But Cousins' throws are not just accurate, they have that softness where the ball is taking a helpful arc as it passes the receiver. It's a subtle matter of a degree or two, but it's almost always in the receiver's favor, making the catch just a little easier to make. This is a large part of the reason for his high completion percentage: his marginal throws are easier to haul in than those of almost any other QB you care to name. It's not only an underrated aspect of his play, I have literally never heard anyone mention it, though it's clear to see visually when you watch his throws.
