Megan Rapinoe....eventually
Is she even top-ten all-time in her sport?
Definitely, yeah. Top 5 on many many lists.
I don't think that is true even among Americans, let alone when you count the world. I think it would be hard to put her ahead of Hamm, Wambach, Akers, Lilly, Lloyd, Chastain, Foudy, the 2 goalies Scurry and Solo, and then you have older players like Jennings-Gabarra, Milbrett, and Fawcett not to mention contemporaries like Morgan and Ertz that are still going strong or defenders like Rampone (now Pearce) that just played forever.
And that is just Americans. You add in the foreign women (you know Marta, Prinz, Wen, Sawa, Sinclair, Smith, Angerer, Riise, Sissi, Sundhage, Parr, Rottenberg, etc.) and Rapinoe isn't even a top 25 player all time and may not even be a top 50 player all time.
