Free Agency of course begins on March 9, but teams are able to contact players that are about to become FA’s two days before that, on March 7. That makes me wonder if the Bills, in selecting March 11 as their do-or-die date, wanted to be able to scour the FA QB market, get in touch with guys they might prefer to Tyrod, and see if they can reach deals with them BEFORE either firming up their ties to TT or cutting him loose. That would be a smart way to proceed.
