What is a futures bet in sports betting?

What is a futures bet in sports betting? So he says, how would you like to be rich? So I said, sure. So he lays this book on me. He says this book will tell me the outcome of every sporting event till the end of the century. All I have to do is bet on the winner, and I'll never lose. So I said, what's the catch? He says, no catch. Just keep it a secret. After that, he disappeared. That was Back to the Future Part Two — Biff handing his younger self tomorrow's scores. He never loses because he already knows. Nobody else does — which is exactly why futures pay. A long-term bet on a season outcome like a championship winner. In plain terms: a future is a season-long ticket — champions, win totals, awards. Your money can be parked for months. “I grabbed Lions futures at plus five thousand back in August.” Let's use this example. In August you take a team to win the title at plus five thousand — one hundred dollars to win five thousand. The ticket lives until the season ends: months of sweat, one grade at the very end. Lines and prices can differ by sportsbook. Nothing here guarantees a result or tells you to bet. Lines move and books differ. Nothing here is a guarantee or a command to bet — it's how the number works.
