Major trades in an NFL draft aren't as uncommon as fans might believe.
Remember the haul the Washington Redskins gave up to make a play for Robert Griffin III? Or look as recent as last year, where the Philadelphia Eagles gave up the big cost to go get Carson Wentz.
The theme, of course, is simple—the biggest trades surround quarterbacks. Seeing as this is an iffy class for signal-callers in the first place, any big deals will center on veteran quarterbacks either set to hit the market or pursuing starting roles with a new team.
