Rivalries run deep in the Ivy League. For instance, Princeton and Penn are longstanding men's basketball rivals; "Puck Frinceton" T-shirts are worn by Quaker fans at games. In only 11 instances in the history of Ivy League basketball, and in only seven seasons since Yale's 1962 title, has neither Penn nor Princeton won at least a share of the Ivy League title in basketball, with Princeton champion or co-champion 26 times and Penn 25 times. Penn has won 21 outright, Princeton 19 outright. Princeton has been a co-champion 7 times, sharing 4 of those titles with Penn (these 4 seasons represent the only times Penn has been co-champion). Harvard won its first title of either variety in 2011, losing a dramatic play-off game to Princeton for the NCAA tournament bid, then rebounded to win outright championships in 2012, 2013, and 2014. Harvard also won the 2013 Great Alaska Shootout, defeating TCU to become the only Ivy League school to win the now-defunct tournament.
