First, apologies for the long reply. Secondly, I shouldn't have said preseason polls are completely meaningless, but rather inconsequential especially for teams in the 15+ rankings.
If you look at preseason Top 25 polls - at least since 2010 - they consistently have anywhere from 9-13 teams that aren't in the final Top 25 poll. That's anywhere from 36-52% of the teams they get wrong. Most of the incorrect teams are in the 15-25 range, but you do have some occasional Top 10 or 5 teams that are unranked by season's end (rare, but it does happen). So, to me the Top 25 preseason is pretty meaningless - especially when you consider the range of rankings that we are considered for at the moment (15-30 range). IMO, teams that are ranked between 15-30 preseason are pretty much interchangeable. That's why, to me, it doesn't really matter where they put us. Truthfully, our ranking will be fine after non conference provided we don't have any N Fla or Garner Webb games.
Now, to your point that polls matter for the Final Four, I agree. To make E8 or F4 you usually are in the Top 15 preseason.
That doesn't bode well for us, but there are some exceptions. Realistically, I think we'll have a strong year, finish in Top 3 B1G, at least Sweet Sixteen, finish - at least - in Top 15 in final poll. If the match-ups are favorable, perhaps E8 and if the stars truly align F4. (also, I think our year will be predicated on how well our guards can play, so the combination of Stephens/Mathias/Hill need to be big for us to have a chance at E8/F4. Keep turnovers to a minimum, consistently make 35% of our 3s, be able to feed the post, solid defense. Not asking for any 18 PPG scorers from our guards, just really solid guard play).
People say early pre-season poles are surprizingly accurate in some respects. I guess if you look at the fuzzy results they predict, they cover a number of widely different outcomes. Odds are that the FF teams are somewhere in the tope 25 list, so I guess that is "accurate"?
