Well, there's another way to look at it.
There are a lot of people arguing that we shouldn't be alarmed by repeatedly mediocre regular seasons, asserting that we always perform well in March.
My assertion is: yes, we should be concerned, because more often than not, those teams are simply mediocre, and are not actually great teams waiting to perform at their potential.
Getting better throughout the season is nice, but sneaking into the Tournament, whatever momentum you may have, doesn't help when you end up paired with the #1 overall seed.
I agree with this to a point. Seeding is important, especially when it dictates location. I'm not sure we beat Michigan State in 2014 without MSG behind us (it's worth mentioning that we were under-seeded as a seven, which actually worked to our benefit that season but also blinds people to the fact that we were in the top 25 pretty much all year).
It's not really about momentum for me, though. It's about being better in March than you are in January. That means grasping schemes that are sometimes complex, tightening your game in subtle ways so that you're accentuating your value as a player, and condensing/optimizing your rotations to align with whatever a season worth of data is telling you.
I'll take being a six seed and losing by one point to a national powerhouse over being a three seed and not having a chance. Last years team wasn't good enough and so they more or less got blown out by Kansas. If we'd lost a 50/50 game, though, then it'd be tough for me to sit here and criticize the overall arch of progress - you'd bemoan the losses that put you in the position of having to play the #1 overall seed opening weekend, but you wouldn't ask for a different team.
For example, even this year, there are teams that can win the title and teams that cannot. Cincinnati is not winning the title. Neither is Baylor. Everybody knows this. Kentucky and Duke might, even though they'll likely be seeded anywhere from 2-6 on selection Sunday. I'll take being Kentucky or Duke in a year where we have some young players (obviously our talent isn't on that level, but in the AAC, we can win the conference tournament) over being say, Butler.
