Why did Bill Belichick originally not speak about the Josh Gordon trade?

Why was Bill Belichick so tight-lipped - even more than he normally is, and that's saying something - about the Patriots' acquisition of troubled receiver Josh Gordon?

MORE GORDON - Hogan willing to help Gordon if he needs it

Perhaps the Patriots coach saw it as a transgression that the Browns put out a press release on the trade Monday before it actually had been finalized.

The Patriots then re-opened the deal and got the seventh-round pick that assured that had been conditional.

So apparently on Wednesday the final unresolved term in the Josh Gordon deal was the Patriots squeezing the Browns to sweeten the pot under a threat that New England would renege.
