I've suggested elsewhere a broader mix of high-ceiling/low-floor and low-ceiling/high-floor prospects, with the added twist of enhanced importance of makeup and patience WRT to reaching projections. Some owners would target guys who start out at 70 OVR but might peak at 78, while others mighttarget the guys who start out at 40 but have the potential to peak at 90 (for example).
The players with better makeup would probably be taken earlier, but you might end up with a gem in the late rounds if you do your homework, spend money on scouting and then coaching, and manage your minors well. Of course, there'd still be plenty of turds in the draft pool, and less diligent owners would still end up with more of them.
