Davidson_Combo_LogoRICHMOND, Va. – The tectonic shifting of Division I realignment has rumbled again, and this time it shook out favorably for the Atlantic 10 Conference.

The league trumpeted the addition of Davidson Wednesday for the 2014-15 season, just weeks after George Mason announced it would leave the CAA and would also join the A-10.

“Davidson is an ideal fit for the Atlantic 10 – as a nationally recognized academic Institution complimented by excellence in a broad-based athletic program — the Wildcats will be competitive immediately. Their success in men’s basketball is important, bringing another nationally recognized brand into the league,” A-10 Commissioner Bernadette V. McGlade said Wednesday in a prepared release.

George Mason will become an A-10 member this summer, restoring a strong in-state rivalry with VCU. It also means the league will operate with 13 full members in 2013-14 and then – presumably – 14 in 2014-15.

In the short and long term, this is a boon for the Newport News, Va.-based Atlantic 10. The A-10 will lose four members this summer, Temple (All-American), Charlotte (Conference USA), Butler (Big East) and Xavier (Big East), but McGlade wasted little time shoring up the league.

From a men’s basketball perspective, which, realistically, is the driver in all this, the additions of George Mason and Davidson should be well-received. Given the landscape of college athletics these days, you could make a strong argument that these were the two most attractive and realistic targets for the A-10. Actually, that’s exactly the argument I’m making. The league adds two strong basketball programs with strong history in attractive TV markets; two schools which have each established themselves on the national scene at different points in the last eight years.

It would be impossible to completely replace programs like Xavier, Temple and Butler in a single year, but these are good moves nonetheless. If you count Davidson, seven of the A-10’s 14 schools finished in the top 100 in RPI last year.
