Yes, I love the "our compliance office does not allow Iowa to do it the way the other schools do" excuse that some of those "connected" (and for being so connected, it is incredible how often they are just plain uninformed about relatively - we're talking NCAA - simple regulations and facts) on the HR love to throw out there with the caveat that they are not accusing any "specific" team of wrongdoing. Very entertaining mental gymnastics.
It's really not that difficult to talk very specifically about what you mean, what you theorize is happening, what your experience has been, in these regards. I've had many posts on the various related subjects and attempt to do this whether it be by relating the actual rules and regulations, relaying relevant personal experience, or even just stating a logical theory using some of the above. You can do this very easily without getting too specific in terms of names and things that may not be appropriate for a public message board.
Yet the "vagaries" are much more popular and appealing for some and some supposedly with some connections. Which leaves me with two possible conclusions if these people are indeed connected. 1) Their connections are really not all that sharp - which, honestly, is a possibility given my experiences with a wide range of coaches, or 2) their connections are indeed pretty sharp and know exactly what and who they are feeding.
