It may take some time to establish a pecking list once the regular season begins in September.Jeremy Fowler, ESPN's Managing Editor, provided a detailed breakdown of Friday's competition:"Betting on Raiders wide receivers in fantasy can be difficult because there is good depth, but no breakout star. Not yet. Las Vegas prioritizes Ruggs Edwards and Hunter Renfrow because each can have their breakouts. Raiders think Renfrow will be one of the top slot players in the league in 2021. The trust between Edwards, QB Derek Carr and Raiders headquarters is palpable. Edwards is in his first healthy camp. He has seen some things. Carr is comfortable throwing Edwards' shoulders in the red zone and letting him outmuscle the corner.Ruggs is the best play, he's too talented to be a bust. Ruggs is being worked on by the Raiders to make defenses feel his speed. They are constantly on the attack from the line of Scrimmage and working on his route-running. To get him moving and compliment the deep ball, expect some quick-hitting and crossers. Ruggs, who has gained 12 pounds in the offseason to be stronger for the Raiders, is also expected to gain more muscle.Six receivers have the opportunity to make an impact, and there is no No. Raiders have no wideout drafted in the top 50 at the position because they don't want one.Ruggs is now the No. 52 WR, followed by Brown at No. According to Yahoo Sports, 55 Other players are not being drafted in fantasy leagues.Fowler's report suggests that Ruggs is the Raiders best fantasy receiver. This is especially due to his big-play potential. Ruggs has the most skill set to compensate for the lack of targets. He can catch a few long passes each week, and even score on a deep ball.Edwards looks like he has the greatest upside to his draft value. He had a disappointing rookie season in 2020, which saw him catch 11 catches in 12 games.Carr said last week that Edwards was "very fun to throw him a ball," according to reporters. "It's been said before, just as Davante [Adams] could just glide through the air. Their body control is just amazing."Renfrow, meanwhile, is worth a look in the final rounds of PPR leagues. His work in the slot might give him the best consistent looks, even though it's only one per game.Brown is the most difficult player to forecast. As the No. 1 fantasy asset for the Buffalo Bills, he was solid. He was the No. 1 wide receiver in 2019, receiving 72 passes for 1,060 yards, six touchdowns, and he suffered through an injury-plagued 2020 season. Stefon Diggs became Josh Allen's favorite weapon.Brown should be No. 1 if he is fully healthy and can play outside. However, a 31-year old wideout whose value is closely tied to his speed will be able to play as a fantasy receiver or flex option every week.Las Vegas is home to Darren Waller, one of the NFL's most talented fantasy tight ends. However, it's difficult to recommend that any wide receivers be taken by the team before the end of drafts.
