i.e. Bowl season, NFL playoffs, March Madness, World Series, etc. etc.
For me personally, I find myself every year never being more excited than I am when March rolls around and its time for conference championship week and the NCAA tourney. There is just something special about it that no other sport can compete with for me. Throughout the year, I definitely watch at least 2x more college football than I do college basketball, but it still can't compete with March Madness for me.
