I disagree that the number #5 NJAC team belongs in the NCAA tournament.
Some years, the NJAC is really good, like last year with Montclair State, TCNJ, Rowan and William Paterson. I think in most years, three NJAC teams belong in the tournament and those are the traditional three powers - MSU, TCNJ, and Rowan.
Putting five teams in the tournament from one conference is rewarding mediocrity. Like in men's college basketball, the Big East or one of the power leagues getting seven or eight teams in.
The Skyline Conference deserves a bid in the NCAA tournament. While they haven't had much success, that doesn't mean they don't belong. This is Division III baseball and all legitimate conferences deserve a chance to compete.
Centenary's appearance in the NCAA tournament the last two years has led to them now scheduling Cortland during the regular season. Cortland in the past has also gone down to the New York-New Jersey area to play St. Joseph's (Long Island), Stevens Tech (or just Stevens), and Manhattanville just to name a few.
While the conference is a whole is on the weaker side, you can't deny them the right to get into the NCAA tournament. What if we said that, oh, well conference A is horrible and they're no better than the ACC or the Big East and the seventh team in that league should be in over a crappy mid-to-low major. But that argument's blasted out of the water by every George Mason, Creighton, and Southern Illinois that proves they can compete on the national level.
On a Division III baseball level, Mount St. Mary, representing the Skyline in 2003, advanced to the third day of the NCAA regionals after upsetting RPI on the first day of the tournament. They lost to eventual regional winner Trinity and then Messiah.
