There were many reasons why BC Baseball struggled for a few years and why the rebound finally came and the biggest issue was talent. This year saw talented players like Dunn make the leap. As long as BC keeps doing that, BC Baseball should be fun to watch.
As for Dunn's future, I think the Mets know what they are doing. They wouldn't select him this high if they didn't think they could sign him. Dunn did bypass MLB when the Dodgers drafted him out of high school. Given how the MLB and college rules go, this probably means he's headed to the pros.
