I think it was Passan or Ken that had an article recently that it's the players that are holding alot of advancements in this area up. If it was up to the owners according to that article they would have free agency dates and a floor.
Plus it was mentioned in the article that Scott Boras loves an offseason like this because his players get paid eventually. He doesn't give a s%*# if this sport gets overshadowed by the rest of the sports during the offseason.
