Many years ago, baseball season began in March. The northern schools went before the NCAA claiming that starting later was a perk for southern schools. So they moved the start date up to mid February. Many schools now have indoor facilities for practice, and most northern schools practice first then give instruction as they move indoors from the cold.
I am not familiar with how many schools actually have indoor facilities, so the D1 programs that are at a disadvantage would be the smaller programs that have no such facility are struggling as is.
It's pretty apparent from watching teams the first 2 or 3 weeks in Florida, that it's actually their first time playing on the field.
However, most teams that travel do so, not always for the win, but for the bump in RPI which can reward them later.
I am a really a strong believer in having two separate divisions for D1 baseball just like in football. Let the big dogs battle it out, without beating up on the smaller ones. Some how you have to make it more fair than it is now, but by changing the calender might not be in the best interest for every program as well as student athlete.
