I'm a little late here and this thread may already be dead but....was cruising around seeing what i've missed over the last few months and this caught me eye.
I'm actually very familiar with campbell since i did go there for a year (back in the day) but I know a lot of alums and some of the coaches...... Just some thoughts from a different perspective...
First from CU's perspective its purely financial. I think this was in a press release but the furthest drive for Campbell in the Big South is closer than their closest opponent in the A-Sun. Back in the day trips to FLA, Alabama (Troy), and other places made sense for campbell because they were going to FAU, UCF, Troy...pretty good schools. Now they are traveling to Florida to play Florida Gulf Coast? Other than in baseball -- why? Football has been mentioned and covered...no need for me to further that. Campbell brings in a solid middle-upper basketball program, great mid-major non-revenue sports (Top 40 Golf, regional respect in mens soccer, good track & field programs,) and should be pretty competitve.
I get that a lot of you seem to think this is marginal addition for the conference .... taking the wait and see attitude. Let me make a brief case for why you are wrong. Money. Campbell has a lot of it. They just built a gorgeous (smaller, yes, but I saw it about 2 months ago...beautiful building) new basketball arena... Their soccer facilities rival ACC schools in the area -- and they should, womens team is down but the mens team competes with regional mid-major powers and usually pulls off an ACC upset every year... But they spend money and have a lot of it. Unless the policy is changed the school has a rule that construction can't begin on a project until 100% of the money has been raised to build it. They just spent $70 million on a basketball facility (
http://www.falconengineers.com/clients/ ... ball-arena ) not to mention the football facilities.... And if you've been there (which i'm sure many of you haven't) they just decided the campus needs a 'better entrance' so they tore up the existing entry roads from route 421 and are wasting millions making some grand brick entrance to campus. Smart? I dunno...But they will bring a lot of money, a growing campus, and a growing region into the Big South... They have tons of money to spend -- and for the most part their athletic facilities will come in and be right at the top of the BSC in every sport (basketball, baseball is above average...older field but indoor hitting facility, good playing surface.... Soccer, softball are beautiful, gorgeous championship golf course, the old gym is a nice volleyball venue... )... Whoever made the comment about Charleston Southern? With the exception of the Baseball stadiums which are similar... (but campbell has a huge indoor baseball/softball facility) I would say Campbell's athletic spending is closer to Winthrop/LU range....than CSU. They spend a loooot of money and it shows.... Charleston Southern's budget is less than a lot of High School's.... I don't know of many high schools that can build $70 million dollar basketball arenas

Not quite the same campbell that left the conference...
The comment was made they are 40 miles from Raleigh but no one knows they exist.... Its not quite that far but actually there are a LOT of Campbell grads in Raleigh. The campbell law school has been moved and is now in downtown raleigh, and the school exerts a fair amount of influence in Raleigh. Raleigh will always be a split NCSU/UNC town but bringing Campbell in DOES bring the Raleigh market into play. In Raleigh its UNC/NCSU and then campbell is the annoying little step-brother... but at least he has a spot at the table. For instance....decent article about joining the Big South again in the News & observer.... No its not front page news, but its press that the Big South wouldn't have in a decent sized market -- so I don't see it being bad at all....
Finally, didn't see an answer to this but...The Campbell board of trustees reaffirmed (when the announcement was made) that the school will maintain its ban on Sunday play (this means Double Headers for baseball on Saturday...no sunday basketball games etc.) but they made provisions for possible exceptions regarding make-up games, conference tourny games, and NCAA games...
