Howie Roseman is not a man who is afraid to trade. When he traded for Michael Bennett this offseason, it was his 14th player trade he had made since the start of 2016. Only one team (Patriots - 18) has made more player trades in that time. So when news came out yesterday that the team was actively making a player available for trade, it wasn't surprising.
When the team brought Chance Warmack in last season, he was expected to be the back-up LG, as Isaac Seumalo was supposed to take a big step forward in his second NFL season and be a strong starting LG. That wasn't the case, as Seumalo lost his job to Warmack early in the season. But Warmack had a hard time keeping pressure off of Carson Wentz, and soon lost his job to Stefen Wisniewski, who ended up being a key piece to the line and kept Nick Foles upright in Super Bowl LII, with Foles not being sacked once in the game.
With 6th-round OG Matt Pryor having a solid training camp, and Isaac Seumalo being versatile enough to play any position on the offensive line, it would be irresponsible not to actively shop Chance Warmack to other teams who are desperate for offensive line help. Warmack's contract is up at the end of the season, so it would be beneficial to the team to try and grab a draft pick now in exchange for him, before he leaves in free agency this upcoming offseason and get nothing in return.
