Hard to say, I doubt these agents get an offer from a team and then just call every other team saying here's what I have in hand...beat it if you want.
I know it's easy to point and say "why didn't the Jays sign this guy for that?" The dynamic at this point is probably Chapman picking a team that he wants to play for and getting a s good a deal as he can.
To be fair, if he opts out after this season, he took less money than the QO was.
