The current Major League Baseball collective bargaining agreement (CBA) expires Dec. 1, 2016. I have chatted with several GMs and execs the past few weeks, and most of them have told me they're resigned to the fact that the game must change and improve to generate more interest for the next generation. That means all aspects of the game, including pace of play and shorter commercial breaks. Although they don't agree with all the ideas being floated, those I talked with are supportive of commissioner Rob Manfred, and many are open to the changes that could take place this offseason.

Here is a look at some of the changes that could be discussed, plus my (informed) thoughts about each:

September roster expansion

There is finally enough momentum for the clubs that want to change the ridiculous imbalance of increasing rosters to 40 players in September to get something done. A significant change might happen for the next CBA.
