After seeing and responding to Benwin's Forum Post earlier this evening, I noticed something interesting in the list of weeks that school's were ranked #1 since the inception of the AP Poll.
OSU - 105 weeks
Remainder of the B1G, based upon their B1G membership.
TTUN - 34
MSU - 29
Minnesota - 18
Iowa - 11
PSU - 6
Northwestern - 5 (yes this is true)
Purdue - 5 (also true)
Wisconsin - 1
For a grand total of 109.
Believe it or not, all B1G teams combined only have four more number one rankings than the Buckeyes all by themselves. I would predict that OSU will pass the rest of the league combined within the next two years.
Other #1 rankings for current league members that were accomplished before joining.
Nebraska - 70
PSU - 15 pre-B1G
Maryland - 6
