Bartoo's biggest problem in the matrix is that he doesn't reevaluate recruiting rankings each year. In other words, the year Bernardrick McKinney and Johnthan Banks were Juniors, they were still 2 stars in Bartoo's matrix. No algorithm will be very accurate if one of the metrics is flawed to that extent.

Other examples, this years team has 2 Star Fitzgerald at QB, 3 Star McLaurin at S, etc....if re-ranked, both would be 4 stars at minimum. And there are many other examples as well. I'm also pretty sure His matrix also doesn't factor in guys that are no longer on the team....so you have an Ole Miss getting credit for Shea Patterson, Van Jefferson, etc.

To me, this not factoring in player development or not re-rating players, kills the matrix completely
