Rivals system is weird. In there defense they are trying to make it as realistic as they can but no system is perfect. We do get points for JUCO players. They get the rankings with a formula that takes into account star ratting also with ratting they get i.e (5.6 5.7 5.8) next they take where they rank at their position. They also give points for being in the top 100, and Finlay for being at a skill position. Then i think they multiply that by a number that depends on your average star ratting in relation to 3.0, so in short it is vary confusing.
We did not move up in rankings but we did move up in points I saw last night that if we get another commit that was worth the same amount of point as M. Couch we would move up to 15/16 in the rankings.
My suggestion if you want to know why we move then use Scout's. I am not saying one is better than the other but you can do the math in your head to figure out their rankings. They only use 2 variables you get X points depending on starts, And Y points depending on rank. x+y=p with P being points, I hope this helps.
