The line is pretty interesting this year. The models and stats like the 49ers (who were one of the most efficient teams of all time, per play, by some metrics) but the Chiefs are clearly in better form (another way of expressing recenty bias). In general, it think it is a fool's errand to pretend to know better than the bookies, and they probably have it right, again.
I have a lineup in the finals of a bestball contest. 400 entries remain. A lot of entires don't have a "full" lineup, as many of their players aren't even playing in the Super Bowl. First place is 150K, but the players I have that are still live are all very popular (apart from MVS and Jennings, so I'm rooting hard for them, and against players I don't have, namely, Purdy, Aiyuk, Deebo, Kittle, and Watson) A few other line ups have all of the same active players left as me, so I can't take 1st place on my own. After some back-of-the-envelope guesses, I think the most I could win is around 60K if things go perfectly. Around 7K would be pretty good aside from very unlikely outcomes.
So, I think I'm going to make an account on FanDuel (which I have yet to do) and take them up on their 5 dollar deposit = 150 in bonus bets (for new accounts). And as a tip to all you degens out there, you can maximize your returns with offers like these by betting outrageous longshots. This article lays out the math (it's talking about free bets instead of bonus bets, but the same logic applies): https://unabated.com/articles/risk-free-bet-profit-strategy
So I'll bet some silly parlays on crazy props revolving around the above named "root against" players so I should have something fun to sweat no matter how the game progresses. Also, in general, the prop markets tend to be the least efficient. You often find more negative expected-value bets there on average, but you're also much more likely to find actual value hidden away in those lines. Prop lines are designed more to entice action than they are to be accurate, at least compared to the more heavily bet things like moneylines and spreads.
