First overall draft picks getting traded for one another

The Detroit Lions traded away their quarterback Mathew Stafford, in exchange for LA Ram’s quarterback Jared Goff, 2 first round picks and a third round pick on January 30th 2021. The most interesting part about this trade (at least to me) is that both of these players were first overall draft picks. Stafford was the first overall pick of the 2009 draft, and Goff was the first overall pick of the 2016 draft.

Have 2 (or more) first overall draft picks (first pick of the first round of a draft) ever been been involved in the a trade in any of the North American big 4 leagues (NFL, MLB, NBA, NHL)?
