Yes, people keep saying this, but I don’t believe the CBA or Boras can drag Cohen into court to enter into a contract that hasn’t been signed/executed, one where the normal process took place (player takes physical, physical reveals issues, contract possibly re-negotiated as a result (the likely scenario here)).
Could see Cohen getting fined by The MLB or some other punishment (loss of draft picks) for “free agent tampering” if it comes to that point, though it would be more for revenge on behest of Reinsdorf and his other fellow Angry Tankers than any principle they may hold, as if.
