The tournament invited him. So clearly he was important enough for them to ask him to play in their tournament.
The only reason they invited him was because of his YouTube presence, so it seems to me that the pga tour is making a stupid decision to not capitalize on the very thing that got him invited.
They wanted his viewers to watch their tournament, yet they weren’t going to let him use that content to bring his viewers to the tournament.
From everything I’m reading Grant doesn’t need to donate his time to help promote the pga tour. That’s not going to benefit him in anyway.
