The CFB season and The NCAA Hoops tourney are real close at #1 & #2.
MLB, the NFL, and the NBA do very little for me.
3. NHL Playoffs. There is nothing in the sports world that rivals a Hockey game where there is "something" on the line for pure intensity.
4. PGA Major Tournaments. Especially the Masters. Whether it was Jack reliving his youth at age 46, crying along with Ben, or jumping as high as Phil did when that putt went in on #18. This is one of the most special events in all of sports.
5. A good dual meet in Wrestling.
