I think you're pretty much on-target with all of these. The other thing I would add is "slow response".
The Browns did rally to answer the story, but it took them over a day, which is an eternity in the age of the internet, and by then it had gotten play on WKNR, local TV, etc. The team doesn't know how to react to these things, I guess... I susoect they first sort of hope they go away so they don't have to acknowledge the existence of the source site, then seem to react once it's clear it's not going to go away.
I really think one of the greatest values the OBR offers these days is an ability to get quick reality-checks on rumors, such as this one, but it took us a few hours to nail it down ourselves.
Lots of bogus info getting out into the media stream these days...
"Slow response". This should be our theme since 1999.
LOL... good one, Vintage... "non-response" sometimes, it seems.
