David Gass brings in the stars to help preview one of the biggest weekends of the season Heineken Rivalry Week. First Calen Carr and Ben "The Research" Baer stop by to talk Houston v FC Dallas (9pm ET on UniMas & Facebook.com.) They chat about Calen's history in the rivalry but more importantly what Wilmer Cabrera and Oscar Pareja are building for the future. They also breakdown the must win Seattle-Portland Cascadia Cup match on Sunday 10pm ET (Fox & Fox Deportes). Plus they look back at a bunch of midweek action and forward to a Saturday night filled with big time MLS battles.   In the second segment Tommy McNammara and Luis Robles stop by the MLS office to preview the Hudson River Derby. McNammara talks about his national team future, NY sightseeing tips, and much more while the ironman Luis Robles takes over hosting duties from Andrew.   In the mailbag the ignorant ETR hosts FINALLY look north to the Canadian Championship, wonder what is wrong with Jordan Morris, and one caller worries Deuce could get Landon'd off next summers World Cup roster.
