Though some bad teams make it through and some very good teams stay home, people should know that the D3 teams that REGULARLY go deep into the regionals and possibly beyond are really very competitive. We're talking about a very high level of college baseball. Though I wouldn't compare such teams to teams that go deep at the D1 level, we are still talking some very serious ball. You shouldn't think of playing for teams of that caliber as an easy thing to pull off.
