The 2021 NFL Draft begins on Thursday, April 29 in Cleveland, Ohio, and the three-day event will fill a huge offseason void for NFL bettors across the country with William Hill Sportsbook offering hundreds of props.

Before locking in any 2021 NFL Draft prop bets, you'll definitely want to see what R.J. White has to say.

White is uniquely qualified to help you crush your NFL Draft bets. The CBS Sports gambling and Fantasy editor has been SportsLine's No. 1 NFL expert over the past few years, returning over $2,600 on his NFL spread picks from 2017-20. 

In his time as a CBS Sports NFL editor, White was also widely recognized as one of the nation's premier NFL Draft experts. Every spring, he put together seven-round mock drafts read by millions, including trades he expects. No stone is left unturned in White's draft analysis.

This is the same expert who, very early in the 2018 draft process, bet Baker Mayfield to go No. 1 overall at 25-1! Over the past two years, White went 4-1 in 2019 and 3-2 on his top five picks in 2020. 

Last season he hit Tua Tagovailoa to Miami (+110), C.J. Henderson Under 12.5 draft position (+150) and hit Over on total CBs in Round 1 (4.5), while saying: "I wouldn't be that shocked to see a team fall in love with someone like Bryce Hall or Damon Arnette or even Cameron Dantzler either." Arnette wound up being the biggest shock of the first round, going to the Raiders at No. 19, helping that prop cash.

Now he's turned his attention to the 2021 NFL Draft and has revealed his best long shot prop values.

We'll give one of White's best bets away: Back Jevon Holland as the first safety selected (+350).

"Trevon Moehrig is the presumed first safety off the board, but the position is similar to last year in that I'm not sure anyone is a lock to be drafted in the first round," White told SportsLine. "I think it's anyone's ballgame and like the value Holland provides, especially as he can also offer teams some punt-return ability right out the gate."

White also likes several other picks with big payouts, and is releasing a MONSTER 50-1 long shot! You ABSOLUTELY need to see his picks before locking in any NFL Draft prop selections.
