Wow, this is definitely starting to seem like the PGA is crossing the line. Its like they can just make vague rules so they can just change them as they go.
What if this was the 1,000th time they've said something to caddies about attire? Is it still crossing the line or is it instilling the rules they have in place? There's a ton we don't know right now. All we know is he was spoken to about his shorts and all we are doing is passing judgement on the PGA based on a law suit by the caddies. Seems premature to me
