This is when the under 15-yard accuracy matters. At 0:16, Ryan just lets one go to a spot that only Julio Jones can go up and get it. He does this repeatedly throughout the year, but this pass alone shows just how talented Ryan is at putting a ball in a single spot.
At 0:45 in the same video above, Ryan puts the ball on Jones again. This time, he puts it in a spot that allows Jones to run after the catch and make a play towards the end zone. At 0:54, he hits Harry Douglas with a huge cushion around him for an easy out route that Douglas gained another 10 yards after the catch.
Ryan's always had this as his biggest strength. While he may not have the strongest arm in the league, he is able to put the ball wherever he wants and can make sure his receivers can get yards after the catch.
