I agree re: conference bias and poll inertia. But it's also important to note that RPI doesn't care about conferences or polls. (This is more of a PSA than a response to you, but it comes up every season so here we go).
It's a mathematical equation based on your record, opponent record, and opponent's opponent record. Essentially a glorified strength-of-schedule with only a mild consideration for actually winning or losing your games. Easily gamed, and often rewards the wrong things. But it's important to the committee.
Agreed on all that you said regarding RPI and its importance to the committee.
The polls are usually heavily biased towards secheat teams which will play into the rpi equation which is why I'm not a fan of this metric.
It's why its important to win or sweep every series that tech is favorited to win cause of the sec bias in the polls.
We are 18-4 and unranked and ugag is 22-2 and has a top rpi and baseball ranking.
ugag has had to comeback nearly 1/2 of their games (Many of those comebacks in the 9th). In a similar opponent, (Ga State) the panthers put up 10 on the mutts and we held Ga State to 2 runs. The mutts could EASILY have 3-4 bad losses but their offense absolutely saved their butt.
I'm not saying we are the better team or should be higher ranked than them, but I'll say this. I think we beat the mutts this year at Truist and there isn't much of a difference between them and us.
Our defense and pitching is better. Their offense is better. Generally when Tech outslugs opponents like ugag is doing, we ended up collapsing.
Give me pitching and defense over offense and I'll show you a team that likely heads to Omaha.
And as an aside, their coach is a tool and leads as such!
