There is two GMs in every trade. So leaks come come from many people just the GMs. When I say we don't hear anything about Buffalo and you say thats because Buffalo doesn't leak then you are assuming no one else from any other franchise is leaking when they talk. Of course there are leaks.
GM Kevyn has made 1 roster move so far and when Buffalo does get involved it does leak. Like Buffalo interested in EP40, Ehlers, Necas, Chyrchrun, heck sometimes we even here the details involved.
The other GM doesn't have some loyalty to Adams not to leak from their side. The assumption that we don't hear anything out of Buffalo because its tightlipped is ignoring the other possibility its because Adams isn't doing anything.
