This exact same argument was made when they buckled on Elliott. And there was not this sudden rash of hold outs.
The biggest reason why? Most guys dont have the clout of a Martin to hold out. Chris Jones is holding out in KC. If the Chiefs sign him, there suddenly won't be a rash of players holding out in KC. We see hold outs all the time from big name players across the league and rarely, if ever, is there suddenly a rush to hold out. Because there are very few players that can hold out knowing their significant importance to the team.
