More players

Okay, back from the gym, back from lunch and about to embark on some afternoon writing (if the girls comply by taking naps).

So I figured I'd get out another player to see if you guys are as sharp as you've been today.

"I played from 1996 to 1998 with Kansas City, though I barely played in '96. I was a first-choice player my next two seasons there, though, before joining the MetroStars for the 1999 campaign. I was a regular in New York for two seasons. I played my last MLS season for D.C. United in 2001 and appeared in 19 games, my lowest total since I played four games in '96. Who am I?"
