3M Open - Johnson/Koepka

Dustin Johnson is the favorite for this week at 11 to 1, followed by Brooks Koepka at 12 to 1, but if you have concerns, that's okay as both are questionable options at such short odds. They have not played like two of the top players in the world, with Dustin Johnson having back to back rounds of 80 at Muirfield Village. Koepka is still dealing with a knee injury, of which he says may never be fully healed.
