Awhile ago I mentioned MLS originals, I mentioned Jaimie Moreno as one of them. I was wrong. Jaimie came in during the 1996 season, he wasn't with DC United to start the first MLS season. Tony Sanneh isn't playing right now (retired?) so that leaves Chivas USA's Ante Razov and Jesse Marsch as the only one's left. As you probably know, Ante had a short stint with Racing de Ferrol in Spain's La Segunda (2nd division). The only other player I could find that's an MLS original is Zach Thornton. He had a short stint with Benfica in 2004.
Am I missing anyone? If I'm not, it looks like they're the last 3 with Jesse being the last player that's continuously been with the league since it's inaugural 1996 season.
