With the signing of Mike Goff last year to the Kansas City Chiefs brought with it many a San Diego Chargers fans who claimed Goff was done. I think it's fair to say he had lost a step in the eight games he played for the Chiefs before a shoulder injury caused a trip to injured reserve.
Though he started 113 consecutive games before his trip to IR, injuries usually don't get better as players get older.
Goff is 34 years old.
This would leave Wade Smith and Andy Alleman as the remaining options at right guard. I like Smith a lot -- Josh Looney of KCChiefs.com regularly touts his versatility -- but I'm not sure the Chiefs wouldn't take this opportunity to upgrade the position via free agency or the draft, where quality guards can be found in the middle rounds.
