some good info here, and ill clarify the rest:
weena is right, its all about the decimal points, just because a #1 pick bumps you up one season, it absolutely does not mean it will in the future. also correct about #1 pick being worth more than #2, etc, etc. hes also right that national awards and POY and such don't directly impact prestige - but to be fair - national AA awards (and nothing else) DO affect your players draft stock. so, a guy who was going to go #12 based on everything else, who is a 1st team AA, might go #5, and thus, your prestige bump does go up. so national AAs affect prestige if and only if the player who got the award gets drafted.
mamxet is right, the prestige bump goes away, and it is after 1 season.
an average lottery pick is approximately worth 1/4th of a prestige grade, somewhere in that .25 - .3 range. i am much more confident in that figure than i ever expected to be, for whatever that is worth. it is possible (although i've only seen it once) to jump 2 visible grades on as few as 4 picks. i ticketed on that occasion to ensure it was not a mistake.
edit: 2nd round picks, its really much harder to pin down, my guess is the best 2nd round pick is .15 or lower. its probably in the .1 ballpark on the bottom end. note, all these scores are in relation to a partial prestige grade value of 1.
final comment. it is my belief that the way to get those A+++ type prestige grades, is possibly more about draft picks that season, than either baseline prestige or recent dominance. i believe the draft picks are just added on the end, and that the gravity that pulls all super A+ grades down, does not apply to draft picks. this, i do not know for sure, but it is my theory on the subject.
