From my very own gray matter, but my intention was never to reveal to you a great mystery about the game of football.

I was merely stating the fact, which sometimes seems to be forgotten or just ignored, that it's very hard to give players a "firm" grade, because a player with a certain skill-set will more than likely have a better chance to succeed in a certain scheme as opposed to another. That is also why the strategy of picking always the BPA in the draft doesn't necessarily work, because although a player might be graded high by the team and/or a "reliable" third party, he might not ultimately fit the scheme the team is working with, which in turn can jeopardize the development of a promising young player and decrease his ultimate trade value (if he is being picked for such purpose, as sometimes happens with BPAs).

Furthermore, I was in fact contributing to the thread as opposed to just sprinkling gay powder on top of it simply because I do not agree with the initial premise the thread is based on.

I myself do put value in some player evaluations and subsequent grades they are given, but it depends on the source who/which is making the assessments. For example, I do value the evaluations of Mike Mayock, because he does know a lot about these young players and he spends massive amounts of time to ensure that he does a good job with his evaluations. Part of the reason is that I don't watch any college football, so I usually don't have any idea about what type of players the draft classes hold, and this is where such "reliable" evaluations are very helpful to such people like I am.
