re Is this a low-key suspension by the PGA Tour?? - No. He likes to play the week before majors, he doesn't like to play 3 weeks in a row. He's playing at the Canadian Open next week.
re Just a little more "smoke" that gives my theory that his illegal driver was more than from "regular use" a little more juice. - It really doesn't.
re I remember a few years back when Dustin Johnson "announced" that he was going to take a six month break from the Tour to recharge himself, and the PGA went along with it until it leaked that he was actually suspended for six months for failing two drug tests showing Cocaine use. - I stand corrected. There you have it. Must be a one week suspension for Rory, nothing to do with his not wanting to play 3 weeks in a row.
re Whenever Rory does come back, if he is not playing as lights out as he was before this situation, you really have to start to wonder.... - Sounds like you've already made up your mind.
