The Eagles’ trade of Matt Tobin to Seattle was surprising when you consider that their top backups at offensive tackle now consist of a former fifth-round pick who struggled mightily last season (Halapoulavaati Vaitai), a converted tight end who went undrafted in 2016 (Dillon Gordon), and a converted defensive end who is in his first year on the offensive line (Taylor Hart).
The negligible nature of the return suggests they viewed him as taking up a roster spot that they needed for somebody else. You don’t part with a player two weeks before the season to move up from the seventh to fifth round of the draft if you envision him serving a vital role.
