The the final chapter of the FC Dallas - Castillo split likely will be its impact on the remainder of club's 2016 season, but the story's big lesson is a reminder that FC Dallas is ultimately in the business of selling players.
The loss of Castillo is an immediate problem. Dallas is, after all, having its most promising season in 21 years. Bottom line, Dallas is not a better or as good a team today as it was three weeks ago when the Colombian popped that rabona highlight versus Chicago, following it up with his final act - scoring the late USOC winner in Houston.
