Because the CBA was ratified last year, it allowed the 4th-overall pick, WR A.J. Green to sign his contract quickly and not miss a day of training camp. This led to him having one of the greatest NFL seasons by a rookie-WR in NFL history. That likely wouldn’t have happened under the old CBA, as Brown would have tried to force a bad contract on Green, leading him to holdout and miss part of training camp after already missing the whole offseason due to the lockout.
Another part of the new CBA is the minimum cash spending rule which dictates that the minimum spend threshold for an individual team has to be 89% in cash of the amount of the maximum salary cap for that year, which takes effect in 2013. Now Mike Brown HAS TO SPEND MONEY! No more low-balling draft picks while letting franchise players like Jonathan Joseph walk without giving them a more competitive offer going forward. More than likely, Brown will adjust to this rule by re-signing players earlier in their contracts to prevent them from leaving via free agency.
