Yes Big 10 is definitely playing catch up when it comes to baseball. For decades, conference wasn't really even trying. They are now, but some ingrained habits don't change overnight. In the past decade, conference has had Indiana and Michigan make the CWS, and Michigan nearly win it. So there is progress. But much left to be done.
Northern schools have been lobbying for a later start date to the season and for CWS to be in July instead of June. That has gone nowhere as the southern schools have zero interest in helping out the northern schools. And I get the suggestions to break off and make a separate league for just the northern schools. It makes sense on some level, but all it will do is grow the talent disparity even to a greater level than what already exists. The top-level talent at the high school level is going to want to compete at the highest level. It's not much of a recruiting pitch to say "we'll compete at not the highest level."
Yes, and this is what I'm suggesting (I take it a step further). Northern schools rarely can compete with southern schools, it isn't a level playing field. When you are starting games in mid February and playing until the end of May it is not ideal for baseball in the north. Playing games up north in March and April are typically miserable, people rarely show up to the games. But there is interest in baseball up north, have the games played in decent weather and fans will show up. In the last series against Indiana there were over 2000 fans on the Friday night game alone, play these games in May and June should generate more interest. Once finals are over they can schedule games every day if they want too.
