The first article shows that five star recruits from the 2004 - 2013 classes have a 36% chance of being drafted and a 41% chance of making a roster. The four star recruits have a 21% chance of being drafted and a 23% chance of making a roster. The three star recruits have a 12% chance of being drafted and a 15% chance of making a roster. The only difference is that there were 873 five star recruits, 1.368 four star recruits and 3,656 three star recruits. The odds of successful college players are better with five star recruits BUT it's still a crapshoot and plenty of two stars were underrated.

The second article shows that more three and four star players end up in the league but it's also a numbers game in that there aren't as many five star players every year. His analysis shows that 13% of five star recruits become consensus All-Americans while 2.4% of four star recruits become consensus All-Americans. Either way, the odds are low for both the four and five star recruits BUT there are more four star players. The analysis here stated that 57% of the five stars were drafted while almost 20% of the four star players were drafted. Overall, recruiting is still a crapshoot since a lot of these guys will not pan out.

The third article is irrelevant since they are comparing recruiting results to the success of teams. The problem with their analysis is that recruit rankings are closely related to the success of the teams offering the recruits. A recruit's rating will go up if a top ten school offers him.
