On top of the Mike Weaver and Brad Winchester signings, management has announced that six players' rights were reserved by issuing qualifying offers. The offers make the players Restricted Free Agents, meaning that if another team signs them to a contract, the Blues have the option of either matching the contract and keeping the player or accepting compensation in exchange for the loss of the player.
Had the players not been given QOs, they would have become Unrestricted Free Agents, free to sign with any team in the league.
The players are Roman Polak, Dancin' Steve Wagner, Danny Richmond, Jonathan Filewich, B.J. (the Beej) Crombeen and Chris (Steve Holt!) Holt.
