Contract talks have stalled between the Panthers and right tackle Daryl Williams, according to Joe Person of The Athletic. Williams is now on course to explore the open market when free agency begins on March 13, barring a shift in negotiations. 
Williams, 27 in August, played in only one game last season after undergoing knee surgery. However, he was solid in 2017 and earned a second-team All-Pro nod.
If Williams walks, Person speculates that the Panthers may lean towards keeping left tackle Matt Kalil, a long rumored potential salary cap casualty. Kalil missed the entire 2018 season a knee issue of his own and is set to carry a $12.15MM cap hit in 2019. On March 15, $1MM of Kalil’s $7MM base salary will become fully guaranteed. Ultimately, Taylor Moton could be the club’s only tackle of note to return.
Also of note – on the whole, Person hears from league sources that the Panthers will apply their limited funds to the second wave of free agency rather than going big on one or two free agents.
I gotta believe the Bills will be all over this one.
He’s gonna get paid, Texans, jets, cardinals, any team that needs tackle help
Welcome to Buffalo!
Raiders have had a revolving door of right tackles so they may be interested as well
