Everything you're discussing is based on a reduced depth of target. He's only down 1.6 yards per target while dropping 5.3 yards in depth of target with a 100% catch rate. If I can throw it shorter to gain close to the same, the same, or more, I'm increasing efficiency. That is exactly what he is doing.
He's second in the NFL in success rate (40% of yards on 1st, 60% on 2nd, or 100% on 3rd) over 10 catches.
