Last year, three of the top 10 picks in the NFL Draft changed hands after the clock started running, and a fourth had been moved by a 2016 trade between the Rams and Titans. That deal was one of two that took place in the weeks leading up to the 2016 draft, as the Rams and Eagles hunted down the top two spots in rapid succession.
All of those deals had something to do with a quarterback. The Bears and 49ers swapped the second and third picks in 2017 so that Chicago could take Mitchell Trubisky, while the Chiefs made a big move from #27 to #10 to get Patrick Mahomes.
