Chicago Bears sign offensive guard Lucas Nix, waive Jason Weaver

This morning the Chicago Bears announced the signing of offensive guard Lucas Nix to a one year contract. To make room for Nix, the Bears waived/injured offensive lineman Jason Weaver.

Nix (6'5", 325) was out of football most of last year, but in 2013 he started 10 games for the Oakland Raiders as an undrafted free agent rookie out of Pittsburgh. He had knee surgery in June of 2014, started that season on the Raiders' PUP list, but was ultimately waived.

Pro Football Focus had Nix down for 666 offensive snaps his rookie year (that's a bad omen) and a -43.8 grade, which was the worst grade they gave out at any position that season.

Keep in mind he was a rookie UDFA thrown into the mix. While at Pittsburgh, he played both guard and tackle, although his most experience came as a right tackle. Many scouts had him pegged for guard in the NFL.

Is this the time when we start thinking of Nix being added for guard depth so Kyle Long can kick out to right tackle?
