The 2018 NFL Draft begins tonight with the Cleveland Browns set to go on the clock at 8 p.m. ET at AT&T Stadium in Arlington, Texas. Quarterbacks Sam Darnold, Baker Mayfield, Josh Rosen and Josh Allen are vying to be the No. 1 pick, while running back Saquon Barkley and defensive end Bradley Chubb are also in the mix at the top.

The NFL Draft has become such a huge event that sports books now offer tons of prop bets for fans to wager on. At one major book, Darnold is a -350 favorite to be the first quarterback taken, meaning you'd need to bet $350 to win $100. Allen is +280, or about 3-to-1, to be the first QB to hear his name called in the NFL Draft 2018, while Oklahoma's Baker Mayfield is 25-to-1.

Before you bet on 2018 NFL Draft props, you need to see what SportsLine stat geek R.J. White has to say. White finished in the top 1 percent of the Las Vegas SuperContest last season. It was no fluke, either, as he also cashed big-time in the 2015 SuperContest, the nation's most prestigious handicapping competition.

In fact, anyone following his NFL picks on SportsLine last year netted nearly $2,000.

Part of his success: White has years of experience analyzing NFL statistics and trends, dating all the way back to Super Bowl XXV. After White emerged as a premier NFL Draft expert, CBS Sports asked him to produce mock drafts starting in 2017.

Now, White has examined every 2018 NFL Draft prop bet available and locked in a dozen best bets. He's sharing them over at SportsLine.

We'll give one away: White is taking the under 16.5 when it comes to where Louisville quarterback and 2016 Heisman winner Lamar Jackson will be drafted.

"The Cardinals (No. 15) and Ravens (16) could both be looking QB, and Jackson would be a great fit for the Bills (No. 12) if they can't trade up," White told SportsLine. "At this point, I'm thinking we get the top six QBs all in the top 16, including Jackson."

White is also eyeing NFL Draft prop bets that pay out 5-to-1 and longer. If they hit, it could mean a huge payday.

Will Darnold be the first QB drafted? Will the top three picks all be QBs? And what draft props should you play to earn 5-to-1, or even higher odds, on your money?
