Scott's, and Velus', drops have more to do with their butter fingers than it has to do with Caleb's accuracy. Those 30 of 35 catches will still require for both to actually catch the ball.
Of course, more accurate targets will give both more true opportunities to either catch or drop the ball because they will be more often in an area to be caught.
"If" one of Velus and Scott suddenly learned how to catch, I would much prefer it to be Velus because he is way faster (4.31 versus 4.44), taller (6' versus 5'10") and heavier (200 lbs versus 177 lbs).
As for the perfection numbers, you mentioned 2 targets and 2 catches per game or 34 catches on 34 targets. That is perfection.
