Remember as a coach you have to work for the entire team. What if a handful of girls want to attend(and are good enough) schools in Arizona and New Mexico, but your team is based out of Oregon? As a coach you have to get the girls in front of those coaches. If there is a big showcase in November/December in AZ that will have 4-5 of the targeted schools at it then you owe it to the girls to play in it. After all, they are playing in the showcases around Oregon for the other girls to be able to get their exposure.
As to priority. I will always believe that the game that you dream of playing in college takes priority. If that is softball then so be it. If not, then maybe a showcase softball team isn't the right fit.
Your talking 1 Showcase Tournament... in this example then yes I would discuss with the BB Coach.... but 3?
