Of our 12 commits, 9 are 4-stars or better (Rivals only has 5). I know most people tend to follow rivals more than ESPN, but I have actually been more of an ESPN fan for the last 3 years.
If you pay attention, rivals rankings tend to trend more in the direction of ESPN as they make updates. One of the best examples is Adrian Hubbard who ESPN had ranked high in the top 150 early in the process. Rivals didn't have him on the radar until the very end, and even then he never cracked their top 150. Now, Hubbard has one of the brightest futures of any of the young guys on our roster. OT Brandon Greene is this year's Hubbard.
Save a screenshot of each sites rankings and you will see rivals follow ESPN's lead. By the way, if you haven't read ESPN's player breakdown, it is infinitely more detailed than Rivals.
