In his 3 seasons in KC, Kevin Hartman has probably been one of the Wizards top players over that time frame, but that time appears that it is at an end. Earlier today the Star had an article about how Hartman still had not signed with the team. Shortly afterward, word came out about the Wizards signing Danish goalkeeper, Jimmy Nielsen. While nothing has officially come out, it's not hard to connect the dots and figure out that Hartman's days in KC are numbered. With Nielsen already signed he's the favorite now to become the number one keeper, although Louis Crayton and Ian Walker are still in camp and likely hoping to still get the number 1 spot. I can't see the Wizards signing a guy like Nielsen and then expecting to sign another player to be the number one guy. And I can't expect Hartman to come back expecting to be a back up keeper.
So what happened with the Wizards and Hartman? My guess is that the Wizards offered Hartman a contract that was less than his previous deal (which was $165,000), likely enough less that Hartman flat turned it down and neither side was willing to come close enough to the other. I'm guessing the two parties are to far apart, which is why KC is looking elsewhere. Again that's a complete guess on my part, but I don't think you'll see many people that will argue with this guess.
So what happens with Hartman now? Based on my previous guess and the current collective bargaining agreement, Hartman's MLS rights will be held by the Wizards for the next two years (The current CBA allows teams to hold an out of contract players' rights for 2 years if they make that player a contract offer). Meaning that if another MLS team wants Hartman they're going to have to trade with the Wizards for his rights. If there's no team that wants to trade for Hartman's rights, then Hartman's choices are limited, he can go to USSF Division 2 like Steve Ralston did with AC St. Louis, or he can go abroad and try to play elsewhere like a Scandinavian country or even try Mexico.
It'll be interesting to see where Hartman ends up playing, but I'm basically 100% sure now that it won't be in KC.
