I completely agree that the phrasing is a major turn-off- including the "you heard it here first" part.
The more important issue is what it does to the trade market. There were 2 teams most-often cited as in the market for a top-tier WR before the draft (Phi, NYG) and two such WRs available (Boldin, Edwards). Philly got Maclin, presumably meaning they're no longer interested, while the price for Boldin has been considered exorbitant.
That leaves the Jints and Cleveland. The 2 got into a staring contest that has continued till now. If another team enters the bidding, the Giants may blink- or the Browns may trade with another team.
Mangini has already shown an interest in his previous players and the dialogue mentioned a trade "involving" Jones and Edwards, suggesting they could/would be merely parts of a larger trade.

Q: I have been hearing that the Jets are interested in acquiring Braylon Edwards. Is there any truth to this? I hope Mangini isn't dumb enough to give them a discounted franchise quarterback and number one wide receiver.
A: No doubt the Jets have to be interested in Edwards. I have speculated that Mangini might be interested in a trade involving Thomas Jones. But he would have interest in others, too, such as Leon Washington and Brad Smith. Ultimately, I don't think anything will happen between the two teams. But I wouldn't be surprised if something did.
