Eight of the last 12 Super Bowls have been decided by one score, leading many to believe that Sunday's 2020 Super Bowl between the San Francisco 49ers and Kansas City Chiefs will be tightly-contested. These teams are no strangers to close games, as 10 of their combined 25 victories and all seven of their losses during the regular season were one-score decisions. On Sunday, your NFL picks can include backing the 2020 Super Bowl spread (Chiefs -1.5), over-under (54), or money line (Chiefs -125, 49ers +105).

Another popular Super Bowl wager is a parlay, picking the spread and total for a payout of nearly 3-1. Both picks must be correct for the parlay to cash, so it's important to make an informed decision. That's why you'll want to see the top 2020 Super Bowl parlay from famed SportsLine NFL expert R.J. White.

White cashed huge in 2017 in the world's most prestigious handicapping tournament, the Westgate Las Vegas SuperContest, tying for 18th out of 2,748 contestants with a 52-29-4 mark against the spread. It wasn't a fluke, either, as he also cashed big-time in 2015, tying for 39th out of 1,727 entries with a 51-32-2 record. 

Moreover, White enters the 2020 Super Bowl on a 14-7 heater. Don't forget, he nailed last year's Super Bowl, hammering New England -2 in what turned out to be a 13-3 Patriots win. "Bill Belichick will do enough defensively to slow down Sean McVay and give the Patriots what could be a fitting end to the dynasty they began in 2002 by beating the Rams in Super Bowl XXXVI," White said then. Anyone who followed him cashed easily.

2020 Super Bowl picks from a proven expert

Now, White has revealed NFL picks against-the-spread and on the over-under for Super Bowl LIV. If you parlay them, you'd be looking at a strong payout of nearly 3-1. You can see his full picks here.

White loves the Under in 49ers vs. Chiefs. He knows San Francisco's defense was more impressive early in the season, as it held eight of its first 12 opponents under 20 points. The unit tired down the stretch, giving up over 20 in its last four contests, but the Niners' offense picked up the slack and led the team to three victories in that span. 

Receiving the first-round bye appeared to revitalize San Francisco, which has allowed an average of 15 points this postseason. Kansas City also proved it is capable of tightening up defensively, limiting the opposition to 17 points or fewer in five of its final six regular-season contests. The Chiefs haven't been as rigid in the 2020 NFL Playoffs, permitting a total of 55 points in their two wins, but 14 were allowed after they built comfortable leads.
