Your opponents' winning percentage is far more important than your opponents' RPI, when it comes to getting a strong RPI out of your non-conf schedule. A lot of people mistakenly think that scheduling a middling or bottom team from a really strong conference will help their RPI, but I'd much prefer to play a sim (or human, for that matter) team that will win 20+ games against weak opposition. RPI is 25% your winning percentage, 50% your opponents' winning percentage and 25% your opponents opponents winning percentage. So how many games your opponent will win is twice as important as how tough their schedule is.
I generally agree here, but what I've often thought about is whether a 13-13 Big 6 team w/a real coach can even out with a 19-7 SIM team due to the last 25% (from the opp. opp. win %). IN other words, the Big 6 team may have a mediocr recorde, but he probably plays a MUCH tougher schedule, so would that make up for less wins than the cupcake Sim team that simply wins more games but plays other crappy sim teams and ends up with an SOS in the bottom 2 deciles? My gut says you're still right to play the SIM teams, but I'd like to crunch some numbers...and just never have. Anyhow, this is why I like to schedule the top human-coached teams in lesser conferences. Kind of the best of both worlds if your team can go 6-4 vs. them or better....imo of course
jdno,
First, I agree about playing lone-human type teams from lower conferences. That's an excellent way to get an RPI boost, especially if you're an elite-level Big 6 team that is sure of winning the vast majority of those type of matchups.
Regarding running the numbers on playing a .500 Big 6 team vs. a 19-7 sim team, I just did a quick example from Knight, which recently completed their latest season.
I took the worst-RPI 20-win team I could find (which happened to be coached by a human): Texas Southern, 20-8 record (.7143), and the 306th rated SOS (.5091). I compared them to the highest RPI Big 6 team that was within a game of .500. That turned out to be Georgetown: 16-15 record (.5161), and the 28th rated SOS (.5901).
If we take 0.5 times the opponent's record and 0.25 times the SOS, we get a value of .4844 for Texas Southern and .4056 for Georgetown. Not even close. Playing Texas Southern and their 306th rated SOS is far better for your RPI than playing Georgetown.
