Niner Noise breaks down three key ones and what to make of them.The NFL’s new CBA passed by a 1,019-to-959 vote, according to NFL.com among various sources, guaranteeing 11 more years of NFL football with major changes at hand. In a USA Today breakdown of the CBA, they outlined the six biggest takeaways.The biggest ones, of course, are the addition of another regular-season game and reshaping of the playoffs, functionally pushing the Super Bowl two weeks. With now 17 games before a four-week playoff, there will be a lot more football to be seen.Another note, that while not specifically related to the San Francisco 49ers organization as a whole, is players will no longer be suspended if tested positive for marijuana. That might be the only true concession from the owners in the entire deal. The players also got an additional 0.5 percent of revenue sharing, a large amount of money given the billions the NFL gives in, but a small amount given the intrinsic value players have towards the product.In any case, the new CBA is now officially passed, which means major changes for all NFL teams, some positive and some negative.For the 49ers, as an organization, the positives seem to outweigh the benefits, especially considering their current position right now.Niner Noise will go through three specific impacts of the CBA that will matter the most to the everyday state of affairs for San Francisco.
