In order of preference:
1) CFB...live or on TV...I'll watch almost any team.
2) NHL...preferably live and in person
3) baseball...live (but not MLB...too expensive and boring...give me my local minor league team any day)
With the protests, NFL is off my list. Never did NBA, but college basketball jumps to #1 in March.
Notre Dame is starting to price itself out of my comfort zone. If I'm going to spend $150 on tickets for a Notre Dame game, I'm sure as hell not taking my family, and the ushers better be handing me a bottle of $100 wine or scotch on my way out of the stadium if the Irish lose. I'll watch them on TV no matter what, though.
