You're correct on that 99% of the time, and I agree with you but if you have 5 that can really play and at least 2 of the 5 has decent size AND they can beat the JV. I'd move them up to JV to let them get stiffer competition hoping 2 or 3 of them would be ready for varsity as sophomores.
This kid is a star. His presence on the field alone makes a difference. Just throw the football his way and he will make the adjustment to the ball. When he was on the field the other recievers mysteriously played better. And of course his play as a receiver opened the game up substantially for the running game, which he was a part of as well. And on defense, it's in your best interest not to throw at him. And he saved many touchdowns with his closing speed. I'm not privy to the problems he was having, but I sure hope he overcomes and it, and it doesn't effect him on the next level. Good Luck to the young man
