Colorado: Kwame Sarkodie (Cleveland City Stars)
Columbus: Stanley Nyazamba (Richmond Kickers)
Dallas: Jeff Rowland (Wilmington Hammerheads)
DC: Greg Janicki and Thabiso Khumalo (both from the Pittsburgh Riverhounds)
New York: Terry Boss (Charlotte Eagles) and Matt Mbuta (Crystal Palace Baltimore)
Interestingly, Rowland and Khumalo were both drafted by MLS teams but didn't stick.
So why a bunch of players from USL2, rather than USL1? My guess is the classic combination of low asking price and potential upside. I doubt any of them will be major contributors during the MLS stretch run, but it certainly never hurts to look at young talent for the future.
