Starting at noon today, teams can talk to agents and not players on other teams.
So, you will get reports of "Player X has agreed to a deal with Team Y." But, you won't get the recruiting visits and such starting at noon.
Although, there are all the FAs that were released (Davante Adams for instance and now Von Miller) that can sign because they are not on contracts that expire on Wednesday at 4pm.
So, you will see action.
One type of thing that I wouldn't be shocked by over the next couple of days are guys like Hollins, Ty Johnson, Q Morris, and Gilliam testing the market by having their agents ask around and then they re-sign with the Bills before Wednesday having gauged the market for themselves.
