During crunch time, nothing beats flipping channels between multiple college football games or Red zone channel for NFL (yesterday was fun).
I'm not a huge MMA fan but betting on MMA is pretty exciting.
NHL Playoffs are the best to watch but i'm not a big hockey fan so hard to watch with no team in the race (unless i have $$ on it)
Many people say college hoops here but that sport drives me crazy with all the fouling in the last 2-3 min of the game which affect the over/under and sides. Or if you are giving 11 pts and the team up by 10 is just holding the ball running out the clock and then decides to throw up a 3 pt shot for shits and giggles
