Only a fool would say "no" before hearing the price.
That said, for the trade to even be possible, Gonzalez would have to either take a massive pay cut or some other Seahawk (Rice, Miller, etc) would have to fall on the sword instead. Maybe Gonzalez sees his team 4 games back in the division and feels it's worth it, but that's not a certainty.
It would also have to be a fairly low draft pick. I'd say 5th round, tops. Gonzalez is on a 2 year contract, but it's understood that Gonzalez is very unlikely to play that second year.
That said, if we got him for a 6th and he took a paycut to get down around $2 million or so, who wouldn't be excited about adding Gonzalez? If there's a deal in place that makes sense, I see no reason to scuttle it. Gonzalez can still play. He's not over the hill. He's a possession ace and if you forgot our QB would not stop gushing about Gonzalez earlier this year.
The Falcons are 1-4. Does that make them "sellers?" Honestly, I don't think so, not yet. But if they are 2-5 when the deadline comes, maybe they give it some serious consideration. A draft pick and maybe $3 million in saved salary for next season for a guy that probably can't help a 2-5 team very much. If they reach that stage, Gonzalez could be a bargain buy for somebody.
