Reigning U.S. Open champion Bryson DeChambeau, world No. 3 Jon Rahm and hometown favorite Jordan Spieth are among the PGA Tour stars looking to shine in the Lone Star State this week at the 2021 AT&T Byron Nelson at TPC Craig Ranch. The final event before the 2021 PGA Championship tees off Thursday in the Dallas suburb of McKinney, Texas. 

DeChambeau and Rahm are the 8-1 co-favorites in the latest 2021 AT&T Byron Nelson odds from William Hill Sportsbook. Spieth is listed at 12-1, and among the other contenders in the 2021 AT&T Byron Nelson field are Daniel Berger (16-1), Masters champion Hideki Matsuyama (20-1) and Brooks Koepka (22-1). 

Before setting your Fantasy golf lineups or betting the 2021 AT&T Byron Nelson, you MUST see data scientist Rick Gehman's power rankings.

With his expansive database of golf statistics, course data and betting odds, Gehman creates advanced models and back-tests them constantly. These models have produced 12 outright winners in the past 18 months and three this season, including Viktor Hovland at 25-1 at the Mayakoba Golf Classic and Daniel Berger at 20-1 at Pebble Beach! 

Last week at Quail Hollow, four of Gehman's top 14 golfers finished in the top 10, including Rory McIlroy, who won the event for the third time to break an 18-month victory drought.

"While his recent results have been subpar, it would be no surprise for McIlroy to find success at Quail Hollow, where he is the only two-time champion," Gehman told SportsLine before the event.

Gehman has been on fire all season! At the Zurich Classic team event in New Orleans last month, FIVE of Gehman's top eight finished T-8 or higher, including Louis Oosthuizen and Charl Schwartzel, who lost in a playoff!

At the Masters, three of Gehman's top eight picks finished in the top five! That included Jordan Spieth and Xander Schauffele, who tied for third. 

Three of his top seven at The Players made the top 10, and at Pebble Beach, three of his top four had top-five finishes! Anyone who has followed his advice has cashed in HUGE!

Now, Gehman has ranked his top 30 golfers for the 2021 AT&T Byron Nelson. We can tell you he is very high on Spieth in his hometown event! The Dallas native won the Valero Texas Open in San Antonio last month and followed that by tying for third at the Masters. The three-time major champion and former world No. 1 has had almost a month off and should be rested and ready to storm TPC Craig Ranch!

On the other hand, Gehman is slightly fading DeChambeau, who is the co-favorite! The 27-year-old had a hectic week, flying back to South Carolina from Dallas overnight after thinking he had missed the cut at the Wells Fargo. Although he ended up in the top 10, the fatigue could catch up to him. The tour's biggest hitter clearly has the off-the-tee game to succeed at the Byron Nelson, but the field offers better options! 

Instead, the golf analyst is backing a HUGE long-shot who comes in at well over 50-1 odds! You ABSOLUTELY need to see who it is, and what else Gehman is saying, before you bet the 2021 AT&T Byron Nelson or enter any Fantasy golf lineups.
