One thing I do in the league where I have 20 mil scouting in HS, I dump the worst prospects to the end of my list.
20 mil HS usually shows me only about 200 players with projections. Of those, the bottom 100 are usually garbage, as in, projected 40 overall. So the last thing I've done, after pre-ranking the real prospects, I nuke the garbage. I don't want to be drafting those guys in the 6th-10th rounds; I'd rather just get a lottery ticket unscouted College player.
Sure I still waste some bonus money finding out if they're any good, but at least it isn't a totally guaranteed waste.
But also like Jtp suggests, I'm kinda wondering if these players are actually not fully scouted by anyone, and they're just random drops.
