following baseball would be very boring and i probably wouldn't if it weren't for fantasy, especially when your team isn't very exciting to follow. unlike most people here, i wasn't really a fan of baseball until i got hooked on fantasy. so i can say the main reason i follow baseball nowadays is because fantasy.
mostly though, i love competing for big money prizes. i think fbb takes way too much of your time (if you play it right) to play for no money, whether i win or lose it's always rewarding and motivating to have a good prize. like this year, i won about $1500 but my big money league team fell from 1st to 3rd place in the final few weeks that cost me winning almost double what i won. i was disappointed, but it was such a fun and crazy roller coaster ride that i have no regrets and loved every bit of it.
