Yes, there were so many great trade deadline deals...that I had to give the honorable mentions their own post. This is where we're up against. Also, because the deal happened in May, I had to disqualify the Willy Adames deal, which would have been #4 on the Top 10. It's already changed the shape of the league, and I already wrote about it. So it goes here.
Here are some other deals that didn't make the Top 10, in order of distance from the top.
