The NPB season is less than two weeks old, so it's too early to know if anything we've seen so far really has staying power.
Once the year is a few months old, and the picture of the season begins to take shape, it'll be possible to go back and mine the first few weeks of play for signs of the trends that have taken place.
While getting off to a good start is important, players and teams come around at different times and the picture that's painted in the beginning of the season isn't always the one you see in the end.
