The 2017 MLS summer transfer and trade window, which ended on Thursday, was one of the most active in league history. Partly due to the blueprint of riding summer acquisitions to rises up the table that Seattle and D.C. United established last year and partly (or, arguably, mostly) due to the influx of GAM and especially TAM into teams’ bank accounts, which allows them to fill the starting XI with quality-but-not-quite-DP-level contributors.
The Dynamo signed two players over the entire window, one near the beginning and one close to the end: Designated Player No. 10 Tomas Martinez and veteran center back Philippe Senderos.
