Seriously, put yourself in their shoes. The season is over, the coach is fired, they're in re-building mode. You want to trade for an older, underperforming D-linemen who's nearing the end of his contract. I'm pretty sure they have plenty of those there already.
And Josh Reynolds? You trade for a 4th round pick who's got spotty production numbers when he does see the field - which is not much unless there's an injury.
