Instead of quoting the few people who have said how impossible it is to improve prestige of a school far beyond its baseline, you're wrong.
Is it easy? No, is it possible, yes without a doubt. It takes more then 1 school / coach to do it but it is possible. I will find a link and add it to the end of this post to my Weber State team that you can use to look at the rest of the conference and their past prestiges to see it in action.
Also, it is tough to get beyond the A- range, but why is that so bad? Would anyone consider Gonzaga IRL more then a B+/A- range school? I wouldn't.
I agree on many points stated, my biggest thing is that I believe baseline prestige should start to change after 20 ish years of a world and use a smaller and smaller portion of 'Real Life Baseline' and more and more of a schools 'WIS Resume' to create some sort of new baseline for a school that helps dictate where the teams prestige lies on the A-F scale.
Weber State linkWe had numerous coaches who did a fantastic job at their schools, gfox, davey, mets, uch, indiansrck, ams, hbmerlin, gomiami, naufan, gw and trustme. It is my all time favorite conference I have played in in HD.
