The last one, which had me confused, is ECU. The next year, we played EIU (Eastern Illinois) at home and beat them pretty handily. And all the games listed are either the MACC or bowl games. Thus, we were playing some pretty great competition.

September 9, 2000 23-17 in the Metrodome. Incidentally, that same Minnesota team turned around and beat #6 Ohio State a few weeks later.

per Arkley's tweet, he's covered Ohio for five indoor games. I gather Ohio hs actually played in seven, total, though:
2000 Ohio 23, Minnesota 17
2006 CMU 31, Ohio 10
2009 Marshall 21, Ohio 17
2009 CMU 20, Ohio 10
2010 Troy 48, Ohio 21
2011 NIU 23, Ohio 20
2013 ECU 37, Ohio 20

So, Ohio is 1-6 overall indoors, and 0-6 under Solich. I seem to recall that in many of these games, or perhaps all of them, Ohio had a major cramping/dehydration problem, especially late in the games. Has Ohio figured out the answer to that? Can Ohio nab it's first win indoors under Solich?

Edit - fixed a typo (was EIU, should have been ECU), and added the Minnesota game from 2000.

“When you’re in a dome in the latter part of the year, you’re in the dome with another really good football team and that’s a factor. In my mind it’s 11 guys against 11 guys. We are practicing inside now which is a huge help, we’ve never been able to practice inside and actually prepare for bowl games before or a championship game inside. We have that ability now and we think that is a huge help so I don’t think it’ll be a problem.”

“As far as cramping goes, you know you’re always concerned about hydration and how you’re working your guys out and I don’t know that we can concentrate on it any more then what we do in terms of getting our guys hydrated properly. We’re always talking to them about it and they cannot come to a meeting now without a bottle of water, they need to drink that while they’re in the meeting and that in itself isn’t going to get you hydrated but it’s a mind set that reminds them how important it is. There are so many articles and so many speakers that talk about how vital nutrition is and hydration and sleep to be able to be on top of your game and to be a great football player. If guys want to reach their potential, that comes across loud and clear to them. I think we have the ability to be a smart football team and I hope that we are but obviously it will play itself out.”

Whoa - in Solich's press conference, someone asked:
"I think Ohio is 0-6 inside domes since you got here. And granted, these games are all conference championship games, bowl game, so the level of competition is different. Has there been an issue in years past with…cramping was a issue before if I remember right…playing indoors? Will the IPF help with that? Is it a non-factor in your mind? Is it just a coincidence? Is there anything to late-seasons struggles inside domes for you guys?"

Solich's answer was:

In regards to that stadium, I think it's pretty spectacular, and an ideal on college stadium. I also like Stanford's new one. Both are similar in size.
