As discussed previously by Luke Winn, while top 100 players don't always contribute right away, the top 10 are rarely busts. Here's a list of Top 10 recruits that are still in college:
While I agree this is more fair than tracking McDonald's All-Americans, there are fewer busts to joke about. You'll note I presented the standard numbers and not the tempo-free numbers. If you just looked at the tempo free numbers (and didn't properly account for the percentage of minutes and shots), you might think John Henson was having a solid year. But the old-fashioned statistics paint the story here. Henson has had a very quiet debut. Similarly, Delvon Roe has been efficient, but not prolific. Everyone else on this list would have to be deemed a major contributor. And indeed, every one of these top 10 recruits who is playing in college has an invididual offensive efficiency rating over 100.
