Kellyn,
It's been a hell of a run. Four years, eleven months and twenty six days ago a kid, barely eighteen-years-old, lined up against Stoke City for FC Dallas. Many of us had seen or heard of Kellyn Acosta in the youth teams, a right back who looked like he'd be a fantastic defensive midfielder - the position FC Dallas suffered in after Daniel Hernandez retired.
AJ, Michel, Je-Vaughn, Erick etc. all came and went but you pulled on the FC Dallas jersey 139 times and grew from an academy kid finding his feet at right back, to a box-to-box midfielder lighting up MLS and staking a place in the US Men's National team with a certain future in Europe.
