Supply and demand.
It’s amazing how a players’ value can fluctuate over the course of their career.
Robert Griffin III was once a franchise quarterback and the second overall pick in the draft.
Now he’s a backup quarterback.
Eli Apple was once the 10th pick in the NFL Draft and a player highly regarded enough to push Dominique Rodgers-Cromartie into a slot corner role.
Apple was traded days ago for just a fourth-round pick.
I could go on and on, but you get my point about how things can change at the drop of a hat when it comes to a marketplace.
