PGA DFS players entering tournaments, cash games, or 50-50s on FanDuel or DraftKings for the 2021 RBC Heritage have plenty of tough choices to make. Investing in Dustin Johnson or Patrick Cantlay is a great way to guarantee production, but each player comes with a hefty price tag on both sites. Johnson is the No. 1 ranked player in the world, while Cantlay has finished inside the top-15 in four of his last seven starts on the PGA Tour.

They'll eat up a large portion of your PGA DFS salary cap right off the bat, so making the correct call on the value of PGA DFS picks such as them will be critical when locking in your 2021 RBC Heritage PGA DFS strategy. Before you enter any PGA DFS tournaments or cash games for the 2021 RBC Heritage, you'll want to see the top PGA DFS picks and daily fantasy golf advice from SportsLine's Mike McClure.

McClure is a DFS pro with nearly $2 million in career winnings, and he's been red-hot on his PGA Tour picks this season. McClure is also a predictive data engineer at SportsLine who uses a powerful prediction model that simulates every tournament 10,000 times, taking factors like statistical trends, past results and current form into account. This allows him to find the best PGA DFS values and create optimal lineups that he shares only over at SportsLine. They're a must-see for any PGA DFS player.

Last week at the Masters, McClure listed Corey Conners among his top PGA DFS picks. The result: Conners secured a top-10 finish at Augusta National, returning tournament-winning value at an extremely affordable price. Anybody who had him in their lineups was well on the way to a profitable weekend.  

In addition, McClure's model is up over $10,000 on its best bets since the restart, nailing tournament after tournament. This is the same model that has nailed a whopping six majors entering the weekend. Anyone who has followed it has seen massive returns.

Now, McClure has set his sights on the 2021 RBC Heritage and revealed his optimal PGA DFS advice, strategy and player pool. Head to SportsLine now to see his top daily fantasy golf picks for the 2021 RBC Heritage.

Top 2021 RBC Heritage PGA DFS picks

One of McClure's top PGA DFS picks for the RBC Heritage 2021: Brendon Todd at $7,300 on DraftKings and $8,800 on FanDuel. Todd is coming off a disappointing showing at the Masters, finishing T-46. However, the three-time PGA Tour champion enters this week's event ranked inside the top 10 in a number of important statistical categories, which will help return solid value for your PGA DFS lineups at the 2021 RBC Heritage. 

He ranks first in driving accuracy percentage (73.54), fourth in strokes gained: putting (1.000) and total putting (82.5). Todd also ranks inside the top-20 in putting average (1.716), overall putting average (1.577) and one-putt percentage (42.70). Todd is one of the best putters on tour, and McClure recommends you lock him in your PGA DFS lineups and look for a big return this week in Hilton Head. 

McClure's optimal PGA DFS strategy also includes rostering Webb Simpson at $10,700 on DraftKings and $11,800 on FanDuel. Simpson, who's the defending champion of this event, is an almost sure-fire bet to be near the top of the leaderboard come Sunday. In fact, Simpson has recorded seven top-20 finishes in Hilton Head and he set a tournament record at this event in 2020, finishing at 22-under par. 

The 35-year-old has also been extremely consistent this season, and he'll enter this week's event ranked inside the top-10 in driving accuracy percentage (71.26), scoring average (69.926) and sand save percentage (62.32), which makes him an extremely valuable PGA DFS asset.
