While there have been a plethora of such trades across MLS history, let's hone in on some of the notable deals to take place within the league in recent years.
It's worth noting in making this list that we looked at players who were active on the US national team around the time of their trade and were already in the league. Several USMNT players joined or re-joined MLS with trades involving player rights, but that's not the same as a Nagbe-to-Atlanta kind of trade.
Dom Dwyer to Orlando from Sporting KC (July 25, 2017)
Dwyer's deal to Orlando in the summer set the market for the Nagbe trade. Dwyer, who, like Nagbe, is a naturalized US citizen and subsequent international, had reportedly received interest from his native England during the summer transfer window but Sporting KC opted to pick up plenty of sweet, sweet allocation cash for the striker instead.
Dwyer recorded four goals and four assists in 12 appearances for the Lions after the trade on July 25. Immediately prior to the trade he played a part in the USMNT's CONCACAF Gold Cup title.
Dax McCarty to Chicago from New York (Jan. 26, 2017)
McCarty really played his way onto the USMNT in 2017 after several years in the cold, but at the start of the year one of the biggest trades in recent MLS memory took place, with the Red Bulls sending captain McCarty to the Fire for a boatload of allocation money. To say there was some hard feelings on McCarty's part in the immediate aftermath would be accurate, but the deal provided an immediate boost to the Fire. After finishing in last in MLS in 2015 and 2016, Chicago finished in third in the Supporters' Shield standings in 2017, with much of the turnaround due to McCarty's play and leadership.
Jermaine Jones to Colorado from New England (Mar. 4, 2016)
Jones' first half-season with the Revs, in 2014, was outstanding. He showed why he was widely considered to be the best American at the 2014 World Cup, helping lead New England on a late season tear that ended with an appearance at MLS Cup. But after an injury-plagued 2015 season in New England, Jones began agitating in the press, and the subsequent trade to Colorado was an inevitable end to an arrangement that had started so well.
Jones suffered another injury-plagued season with the Rapids in 2016, but he paradoxically showed how influential he was while healthy, frequently deployed as a surprise No. 10 for Pablo Mastroeni's squad as they just fell short of the Supporters' Shield in a stunningly successful one-season turnaround.
Eddie Johnson to D.C. from Seattle (Dec. 17, 2013)
Johnson's story is one of the most bittersweet in American soccer. The striker broke out with a bang in MLS in Dallas and Kansas City, then got the big move to American-friendly Premier League side Fulham in 2008, with his star on the rise in USMNT circles. But he rarely played in Europe, and was seemingly on his last chance and well out of the national team picture when he joined the Seattle Sounders ahead of the 2012 season. Once again, he showed how effective he could be in MLS, and Johnson played his way back onto the USMNT while with Seattle.
But during the 2013 season, Johnson began publicly asking for a better deal, and was traded to D.C. United after the season. He had a solid 2014, but a heart condition forced him to step away from the sport for good the following year, closing a playing career filled with highs and lows.
