Last night I caught a little of this show SiriusXM This Week in College Baseball. They were interviewing a former member of the selection committee. He said to him the selection process is one of science, RPI. and art, eyeball and smell test.
He greatly discounted mid week games because in regional play you will be facing the best players of both teams like conference and week end games. Mid week games you have a lot of testing and allowing people some playing time. I suppose that is the smell and eyeball test because the numbers are the numbers.
Other things he said was generally true. Prime players getting hurt late not held against teams, and stars coming back late is a plus for team. He regarded how you compete in your conference important. Finally picking the last few at large teams always leaves concerns that they might have made a mistake.
By his logic the win against LSU is no more important than the loss to UNO, both mid week games.
