The Carolina Panthers' contract negotiations with representatives for right tackle Daryl Williams face a "monster gap" financially between the player and the team, a source close to the process said.
A league source said Tuesday that it would be "shocking" if a contract extension happened for Williams before training camp in July.
Williams, a fourth-round pick out of Oklahoma in 2015, is eligible for an extension before training camp. He started all 16 games for the Panthers last season and played every offensive snap, finishing the year as Pro Football Focus' highest-rated right tackle and with second-team All-Pro honors.
