The line has been at Ohio State -6.5 all week after initially opening at -7.5. Within the past hour the line has fallen to -5.5 at most sports books, with Caesars Palace giving us the most favorable odds at -5. I can't imagine the line would be tightening if the insider buzz was that O'Korn was starting.
Update 6:45 PM EST: Two more sports books (in addition to Caesars) now have the line at -5. Update 10:30 AM EST: Twelve sports books now have the line at -5.5 or lower. Two have it at -4.5.
