On June 17, Utah accepted an invitation to join the Pac-10 as its 12th member, and on September 21, Colorado and the Big 12 reached an agreement to allow Colorado to join the Pac-10 a year earlier in 2011. As a result, Colorado and Utah revived a long-dormant rivalry with each other, which has since been dubbed the "Rumble in the Rockies". In 2011, the SEC announced the addition of Big 12 members Texas A&M and Missouri as its 13th and 14th members, both of which officially joined the conference on July 1, 2012. These moves set off the second wave of major conference realignment, as the Big 12 responded by adding TCU (left out of the initial 1996 expansion of the Big Eight Conference into the Big 12) and West Virginia in 2012 to retain a total of ten members. Several other schools have been rumored as potential expansion candidates for the SEC, but the conference has not expanded beyond 14 teams. In light of realignment rumors, the ACC voted unanimously to raise its exit fees to $20 million on September 13, 2011. On September 18, Big East members Pitt and Syracuse officially applied to join the ACC and were accepted later that day, giving the conference 14 members. Both schools ultimately negotiated a buyout that enabled them to join the ACC in 2013. On September 12, 2012, the ACC announced that Notre Dame would become the conference's 15th member in all the sports it sponsored except for football, although as part of the agreement the football team will play five games against ACC opponents each season. There remained speculation regarding the timing of the change until March 12, 2013, when it was announced that the Big East would allow Notre Dame to leave for the ACC after the 2012–13 academic year. At the same time, the ACC also instituted an even larger increase in exit fees, set at three times the conference's annual operating budget (for 2012–13, the fee would be roughly $50 million). In mid-November 2012, however, the landscape had changed, as ESPN reported that Maryland, a charter member of the ACC, was in "serious negotiations" to join the Big Ten. Big East member Rutgers was also reported to be in consideration to join the Big Ten at the same time. On November 19, the Maryland regents voted to accept the Big Ten's membership offer, and the Big Ten presidents unanimously approved Maryland's entry later that day. Maryland would officially join in July 2014. Rutgers announced the following day that it would also join the conference in 2014.
