Gotta Love the RPI

So Seth Davis probably thinks that Wyoming is more deserving of an NCAA at-large bid than Iowa.

Yes. They play in a conference with the highest average RPI in the country and they lost to a team coached by Steve Alford, three-time MWC Coach of the Year.

Next?
 
What Iowa needs to do is schedule teams from the crap conferences that will win their conference. I like how these so called experts talk about the RPI and the SOS being two different things. But guess what, both are derived from the very same numbers, wins and losses. So, if you understand and manipulate the system, you play teams in the non-conference that are predicted to do well in their conference, but, only play one team per conference. It hurts you dramatically when you play 3 teams from the MEAC that all play each other. Look at New Mexico's schedule, they have it figured out because nobody in their non conference cannibalizes each others numbers.

That is not true. There is no weight in RPI to who you beat based on where they are ranked. Iowa's score will change, because of that game, albeit pretty microscopically.

An win over team #300 and a win over team #1 counts the same in your W-L part of the RPI score.

Iowa's Opponent Win% goes up by a game because ISU won. Another win because of Illinois, and down 2 losses because of Minnesota. Plus the ripple effect of those records in opponents opponents Win%

It just goes to show how some of the smaller conferences, with the Mountain West being the leader, are manipulating the RPI system in their scheduling. If you take any of the MWC teams, or even Minnesota for that matter, there are no differences between their schedule than Iowas with regards to teams that they should beat, teams that they will probably get beat by, and teams that are a toss up.

The end of this post is so true. Right now the only reason we are in a position where we have to win 2 is because of our non conference SOS being "so weak". And the only reason its "so weak" is because the bottom 5 teams are all the way at the bottom instead of most of the way at the bottom like everyone else's. Sounds like a legit reason to leave someone out to me.

If that was the case then Iowa's score should have went up since their opponents went 2-1 today and it did not move a mil.

Iowa played Minnesota twice. Their record counts twice. So technically their opponents are 2-2.

Is Iowa's opponent season Win% under .500? If not, then 50% of Iowa's RPI should actually go down.

Plus you have the opponent's opponents records to factor in, which could be impacted by just about every game so far.

Iowa did move up in the RPI when the Iowa St win was entered, however, it went down by the exact same amount when Minn lost. Remember we played Minn twice, Ill once. Our Opp adjusted win %, which is 50% of the stupid RPI, is 2-2 today.
 
So all you have to do is play teams that pile up a bunch of wins, it does not matter who it is against (D1 ofc).

Yes. See below. You don't get extra credit for beating "good" teams. There is no difference for the W-L part of RPI in a win over Wisconsin or a win over Penn State.

It's because of a common misconception about the RPI. All wins count the EXACT SAME in the W-L portion of the RPI formula.

There is no extra weight to a win against Indiana, or extra punishment for a loss to Stony Brook. Now, good teams obviously bump up the SOS part, but it is the same bump whether you win or lose.

If Iowa went 0-31 or 31-0, 75% of their RPI score would be exactly the same.

If they were 1-31, their RPI would be the exact same whether the lone win was at home to Indiana or at home to S Carolina St.

Only 25% of the RPI score has to do with wins and losses and 0% of that is who you beat.

So technically we would have been better off if Minnesota had won against Illinois, right? Since Iowa played them twice.

You know there's something wrong with a system that say you can go to Cameron Indoor and get throttled by Duke by 50 points and have a higher RPI than a team that plays Howard at home and wins by 50.

I actually like this as a fan of seeing the best basketball game possible.

I have zero interest in watching Iowa play 5 home games against Howard type teams while wining each game by 35. I would prefer to see my team play at Duke. This is good in that it stops teams from scheduling complete crap non conference games a little.

I am actually of the opinion that they should elminate at least 75 D1 basketball teams.

Wyoming loses to New Mexico and goes from 70 in RPI to 66 in RPI immediately after loss. Minnesota loses and goes from 23 to 29.

How can you lose to a team in your conference and increase your RPI?

Same thing happened to Iowa when we played Indiana. We went up quite a few spots.
