As far as I'm concerned, unless it's from Whaley's mouth or a done deal, it's not strong.
Look at the fiasco yesterday. The poster said that Fred was informed two nights ago he'd been cut. Then, he wasn't. If he had said, "my source says the plan is inform Fred tonight and give the news tomorrow," what would have been the difference, besides being less incorrect? We aren't placing bets here, we're just getting a feel on the pulse of the organization.
The "strength" of the info doesn't really matter to me, as long as it IS info.
