I think it needs to be made clear exactly what MJ stated.
Cardinals have not announced anything not because they want to wait for a big press conference, or because they are keeping things secret, or something like that, they have not announced anything becuase they are not allowed to under the rules.
Per a memo from the league offices, that he had right in front of his face, teams are not allowed to officially announce any signings of RFA's, EFA's, their own UFA's, another teams UFA's, or trades until 3pm tomorrow. The only thing they are allowed to officially announce are UDFA's and rookie signings.
The only reason we may be hearing about deals as we speak is because of loose lipped agents leaking something or a player tweeted it.
Also MJ only stated that we have signed other guys fans do not know about. He only mentioned Lawson as a guy we were negotiating with, he also mentioned Big calling coach, mentioned that he knows Davin Joseph wants to possibly play here and had his agent call us. He only mentioned Jones and Tulloch as guys he likes, but he usually doesn't keep bringing up a guys name unless he knows we are interested.
So lets be clear, we cannot announce any deals until 3 pm tomorrow per league rules, he knows we have signed more then fans realize only knowing who we have contact he doesnt know who has been signed, and he mentioned some names we have been in contact with.
