Per Pete Thamel of The New York Times, Missouri leaving the Big 12 for the SEC is now "inevitable and imminent," but there is no timeline for it to do so. Should that go down, the Big 12 will likely look to replenish via the Big East (or rumored soon-to-be Big East members), which could hurt their chances of retaining an automatic BCS bowl bid.
The Saints were 2016's oldest team, and the Rams were once again the youngest. Are more rookies starting than ever before in the NFL? 2016 was the youngest season we have tracked yet.
