FC Dallas are US Open Cup champions! That’s awesome. It really is. It just can’t keep Andrew from being more excited for the return of Pescadito. The legend is back to help Oscar Pareja and the boys go for the treble. There’s plenty at stake this weekend as well, with FOX picking up a couple games on Sunday and a must-win Saturday for all three Cascadia clubs.  Prepare to be inspired by a wide-ranging interview with Chicago Fire goalkeeper Matt Lampson, who was diagnosed with Hodgkin’s lymphoma as a 17-year-old. He fought a brutal batter with cancer, and he won. Now, Lampson tells his story and explains how you can help via his foundation or MLS’s Kick Childhood Cancer initiative.    In the mailbag, the guys impromptu brainstorm a new coach for Canada, talk Toronto FC treble and the race for 2017-18 CCL spots and debate the real meaning of “world class.”
