The NFLPA has indeed looked into the matter, Jason Cole of Yahoo! Sports reported Friday. He wrote that the NFLPA has talked to CAA about the situation, but that it is unlikely to be viewed as a violation because of Jay-Z and Cruz's longstanding friendship.
Forbes.com wrote about the matter Friday in a smarter fashion than I could. The article notes that CAA confirmed that Jay-Z brought Cruz aboard to the agency. That would seemingly violate the NFLPA's rule enacted in June 2012 that agencies are subject to sanctions if they (1) use, (2) associate with, (3) employ or (4) enter into a business relationship with any non-NFLPA certified individual in the recruitment of prospective player-clients.
Forbes detailed a few complaints from agents via Twitter. Those complaints continued Friday. Here's one of the nicer ones:
We emailed the NFLPA for comment, but we're still waiting for a response. It's hard to imagine the NFLPA making a big issue of it because CAA (not to mention Jay-Z) is so powerful.
It's also hard to imagine many reporters digging into the issue because so many rely on cozy relationships with high-powered agents for information. It doesn't get any more high powered than CAA. These types of stories usually go away because people in high places want them to go away.
