The player may be fine. In fact, the jets may end up with 2 superb safeties. But the strategy is peculiar. You stack one positional group (like DL and safety) at the cost of all other ones. Then when it is time to resign them, you end up with the issues we now have of overpaying guys in DL and being unable to trade others. Will we spend big money to resign 2 safeties in 4 years? Or should that money be distributed throughout the team?
Simple allocation of resources, regardless of how good the players are.
