They entertained the notion of trading Harbaugh within the last 8 weeks. I wouldn't say it disappeared.
Within the last 8 weeks, I've entertained the notion of:
*Growing dragon wings and soaring across the countryside, using my flaming breath to roast website trolls and propagators of unfounded internet rumors.
* Assembling a group of 32 midgets, 16 African-American, 16 Caucasian, dressing them up in medieval garb and using them as a living chess set.
* Having a portrait of the prophet Muhammad tattooed on the shaft of my Johnson.
My entertained notions are as likely to happen as the entertained notion you're subscribing to...
