For Aaronson: Oh boy, this is a risk. In the short term, maybe it isn't a huge one, as USMNT manager Mauricio Pochettino clearly doesn't see MLS as a hindrance for any player in the national team. For his development, though, it's tricky because Aaronson seemed so close to a legitimate European breakout. He dominated in the Eredivisie last season for an okay team, but, instead of climbing the ladder, he headed back home to MLS. Now, there is a benefit to that as while the pressure to start won't be there, the pressure to perform will be. Aaronson now can't just be a piece; he has to be a star. Maybe that'll help his USMNT case. Grade: C
For the Rapids: They probably can't believe their luck. American stars come back to MLS all the time, but few do so at just 21 and, if they do, it's because they failed abroad. Aaronson surely didn't. If anything, he looked ready for a step up. Now he's a Rapid, giving Colorado a young, star playmaker to build around, and perhaps even sell for triple what they paid in a few years. It's a statement signing for the Rapids, who are now tasked with filling out the team around Aaronson as their centerpiece. Grade: A+
For Eintracht Frankfurt: Dino Toppmoller, Frankfurt's head coach, wasn't dying to get rid of Aaronson. In fact, he welcomed him as a competitor for minutes. When Aaronson asked to move on, though, the club was willing to help him, with Toppmoller going so far as to say he hopes to welcome him back someday. While that may or may not happen, Frankfurt still did make a small profit on the 21-year-old midfielder, even if he never reached the heights with the club that many expected because of this big decision. The club has emerged as a top-tier talent developer, having previously sold Hugo Ekitike, Randal Kolo Muani, and Omar Marmoush for big money. For them, it's onto the next one. Grade: B
