Basically what the grading system means is to grade a prospect using the percentage scale You divide your score by the total score possible and you get a percentage. In this case you multiply whatever score the prospect gets by 2 and you have their percentage. Then you just follow the following scale:
100% A+ (Highest Prospects)
90%-99% (Same Round)
80-89% (-1 Round)
79%-60% C (-2 or 3 Rounds)
59%-40% D (-4 or more rounds)
39%-0% F (Undrafted)
What does it mean:
I have had some questions on how the grading system works. The grading system is all about comparisons and standard evaluation. The top receiver in the class is always graded first. In this class Justin Blackmon is likely to be the first WR drafted. My evaluation of him has him scoring a perfect 50( Size is rounded because of his physicality and chiseled frame) and an A+ grade. However the top receiver will ALWAYS score a perfect 50 no matter what. You then take his expected draft position (Top 10 Pick) and then you can come evaluate that an A+ in this 2012 class equals to a top 10 pick.
This is because if the top receiver in the draft is evaluated based on how he compares to other players in the draft then it helps you to evaluate the value of the other players at that position. If for example the class is weak and the top receiver receives a perfect A+ on our scale (because he always will) but is only valued as a 2nd round pick then the rest of class will follow in value. Now receivers in this hypothetical class that score Bs will be valued at 3rd round picks in that year as opposed to 2nd rounders in this draft class.
You then apply this to all receivers after evaluating the first receiver. For example Greg Childs scored a 46 on our standard evaluation ( 92% and A- Grade). He scores an A- Grade. Now since the top receiver (Justin Blackmon) in this draft is valued at a high first round pick and scores an A+ in this system then Greg Childs will be valued slightly lower or a low 1st to early 2nd round pick because of how he compares to the top receiver in the class.
After you calculate all this you arrive at the players Total Value. This is how much the player is worth to ME. I will then take that and compare it to the players' Estimated Value, the amount worth to OTHER TEAMS. We then want to find out a players Composite Value. We find composite value by subtracting a players estimated value from their total value. Since Greg Childs is worth a 1st round pick in our grading system but is only worth a third round pick to others then he receives a Composite Value of +3 (3-1=2). The lowest composite value possible is 1. This all culminates into a Relative Value of +2/92(184). A players total score is his composite value followed by the original Number or Overall Grade given in the film studies and then the product of the two numbers. This is important because Now we know that Greg Childs is a great value because he is worth 2 more round then his predicted draft spot, has received a total grade of 92 and that culminates into a total score of 184.
Total score is important because it accurately grades a player's value. If a player is worth a 4th rounder to us but is valued at a 7th then the player will be given a +3 composite value. However if he is worth a 4th rounder in this draft then he is most likely graded out at around a 60 or below. This prospect then will receive a total score of +3/60(180). What this means is that this player has a lot of value but also because his original score is so low (60) he is only a relative value because although he is a good value in the 7th round he is still only 4th round talent.
Basically you can stop whenever you want. You can take the players score, compare it to the top player's and know how much the player is worth. However the way the system is set up, we can also get accurate Relative Value scores which will help us determine how good a pick was.

Thanks for reading. I hope this provides a better understanding of what I hope to work towards come early April. We will have a terrific and in depth look at the talent and value of these receivers. When I release my final article, it will contain a comparison of all these numbers and we will see which prospects are better than each other but we will also see which ones can be great picks because of their low value to other teams. Please comment if any questions and again thank you for reading. Aloha!
