Howard Saffan knows 1000x better than myself.
He did all the negotiations for six months in 2010-11 leading to Charles Wang becoming manager of Webster Bank Arena that hosts Bridgeport Sound Tigers hockey.
I'm aware of Mr Saffan's comments to the Ct Post in February 2015 as to how he reads the lease that it's AHL or better, and beatwriter Michael Fornabaio's views/articles on this subject.
However the documents unanimously approved by the Bridgeport City Council on 2/16/2011 only say "Professional Hockey League."
Because I had a mailing list everything is documented back to Roe Boe's agreement with Bridgeport from day one so there is a lot to digest over the years but not impossible to follow.
