For me, historic classes are generally determined after the fact. You have to see what the players become as pros to make that determination IMO. I tend to look at the volume of prospects when coming up with a value for a draft class. I like top 10, top 32 and then top 100. Mix it all together and compare to other classes. This draft class is good because of it's top 100 volume as well as it's potential for top 32. Top 10 is lower, but I feel that is because of the ? of some of the players who would potentially be in that group.
