If there ever is an actual split between the Power 5 and the Group of 5, then this will eventually happen naturally. According to the various pre-season polls for this year that have been released, the only Group of 5 team getting in the top 25 is Central Florida which is understandable. The coaches' poll didn't have any Group of 5 schools in the top 25 but had votes for Central Florida (#28), Marshall (#37), BYU (#38), Boise St (#39), UL-Lafayette (#41), Cincinnati (#43), Fresno St (#46), Houston (#48), and Northern Illinois (#52). Maybe the real story is how 52 different schools got votes.
Anyways, I think this is a an awesome idea in theory. It does give us something to do while realignment is cooled off for the season. It also helps us evaluate who may be on the block for moving up to a better conference. People may say this is not relevant, but look at Southern Miss. They were a very solid program for years. The American Conference sort of formed overnight and Southern Miss was excluded and I'm sure their lack of performance on the field had something to do with it.
However, it would require people paying attention to many games that wouldn't even be on TV so we'd be voting simply based off of box scores which is a dangerous practice. I believe most (if not all) of the coaches vote this way which skews the coaches' poll because sometimes a team can absolutely dominate a game but only win 14-3 and not be ranked as highly as they should. It happens. My other issue would be how weak the programs would be in this new top 25. According to http://www.realtimerpi.com
" onclick="window.open(this.href);return false; (only source I used for this post and strangely places Bowling Green in the top 25...), we would get down to #73 before we had a full top 25. That would be about 57% into the total number of FBS teams. On a side note, #74 on the RPI list is North Dakota St (FCS).
I think it'd be better if we did a top 10 or 15. I would definitely be down for that, but I would also be okay with top 25.
