Good god man, you like to argue just to argue more than I do!! I am trying to help you out here, so I'll be polite about it. Click on this link again that I supplied.

See at the top, right above the #1 ranked recruit, it says "247Sports Composite" and "top247". They are 2 different things. The top 247 is their own sites rankings of the recruits. The 247 composite is the combined ranking of the recruits taking the Scout, Rivals, 247, and ESPN rankings and combining them into an average. You click on both, and you get two different lists/rankings.
So yes, they do their own rankings, and in them Nunge is #109 and Garza is #119, both 4* rankings. Their composite rankings are lower than that and are a 3* composite ranking.
