Obviously I don't see the ads you guys do so have no idea if it's excessive. Not sure how it could be so, it can't take long to film and ad surely? What little of RF I have seen (PGA Tour coverage is notorious for only showing players at the top of the leaderboard, even in Majors) he doesn't look comfortable on the course. Maybe working on (and through) swing changes to make himself more competitive?
I don't know for sure but if so, considering Faldo went through a couple of iterations of that process that led him to several Major wins, I'd expect him to be more ... understanding. Also, given his life experience of unfriendly media - he once thanked them "from the heart of my bottom" while collecting the Claret Jug ... poacher turned gamekeeper for me.
Maybe he's being prompted to be a bit more "controversial" (golf commentary/punditry is notoriously bland); let's see if he targets more than just Fowler in the coming months.
