Here's what You Oughta Know for the final round of the RBC Canadian Open, where Charley Hoffman leads (although that may not be a good thing) and Sam Saunders is trying to follow in his grandfather's famous footsteps.
• Seven of the previous eight winners of this event trailed entering final round, the only 54-hole winner since 2009 to win was Brandt Snedeker in 2013.
• Hoffman is sitting on his fourth career 54-hole lead/co-lead of his PGA Tour. He has failed to convert any of previous three and is a combined 9 over in those final rounds.
