FYI about Sportbet.com. This is NOT a Las Vegas Sportsbook. The Sportsbooks here in Vegas DO NOT place lines on FBS -vs- FCS games. This is an OFFSHORE site, which does it's best to make people think it is in Las Vegas.
As far as the point spread, I see this is more of a knock on Illinois than anything else. Illinois has had a few rough seasons in a row. It is the first game. Given that colleges do not have scrimmages or exhibition games against other college teams, it is really hard to know what to expect from the first game of the year.
I see no real reason to believe YSU will win this game. And, yes, I remember the PITT game. I also know YSU was not starting a new QB against PITT. I know that YSU is 1-8 in these "money games", and even though Illinois is a bottom level team in the BIG 14, they have NEVER lost to a school from FCS. Add that the game is at Illinois, and by virtue of 22 more scholarships and recruiting for a conference schedule in the BIG 14, they ought to have the depth and superior athletes overall to win. Anything can happen, that is why the games are played. I'm just not buying into any hype that YSU will win.
