If this is ONLY a preseason thing, we are fortunate as it may allow some of the young players the team is thinking of replacing him with reps at LG. If this extends beyond preseason, we are screwed as far as the running game goes on the left side. I like Jones, think he will eventually be a solid starter but I can't see him doing great at LG, although part of that might be remembering his less then stellar performances from last year and the last preseason.
