[JRT2006]

Two more drafts and I should have the necessary data to make judgement on the grade values.

Few things: grade values are equal among positions, a 76 rating in speed is a C for WR, a 76 rating in speed is a C for offensive linemen. So the grade values can remain equal among positions.

The difficult part is determining how to place a value on the grade if the ratings are like so:
F=30-55, D=50-75, C=65-80, B=75-90, and A=85-100

Do take the average of both numbers (F=42.5, D=62.5, etc.) which still leaves some mystery to how good yoir player may be. Or do you adjust the value based on the likelihood of having a higher rating to a lower rating.
