Davis was 6'10 with a 7'4 wingspan, and only 214# at the NHS.
Richards was 7' with 7'4, and 240#.
There are no solid numbers on Davis' vertical because the USA team doesn't participate in those, and Davis skipped the athletic portion of the combine. But some reports have his vertical around 35.5" same as Blake Griffins'. Keep in mind that is his max (running) vertical. Richards standing vertical was 30" at the NHS. That puts him in Davis' athleticism range. Now all he needs is Davis' skill, timing, quickness, and instincts..........
