You're getting the self-scout from a player, and it happens at all levels, not just D1A; it's also been around for quite some time. It occurs when the player you're looking at is on the low end of either your vision (in all levels except D1A), or his abilities aren't quite where the SIM thinks they should be for a given level.
If the player mentions upside, he's above average potential, with a slight chance of being Sky's the Limit (you'll need an HC scout to know for sure if he's STL).
If the player says his motor never stops running or he gives 110%, he has average potential.
If the player mentions reaching or nearly reaching his potential in high school, he's below average with a slight chance of being tapped out (again, you'll need an HC scout to know for sure).
