I am a little more wary that his decrease in production is more to the body breaking down, whether it is back or knee or age or a combination. That said, there are a number of other reasons to hope that is the case. The concussion, even if he was not having overt symptoms,baseball is such a reflex sport, it could have been affecting him without him even being aware of it. Also, even if he had no concussion symptoms at all last year, it took away a good chunk of being able to do anything on his off-season. He was learning a new position. That would not only be mentally tasking which could effect his offense, I heard a couple of people say speculate he was trying to hit more like a traditional first baseman and was not playing to his strengths. The fact that he felt pressure to make the home all-star game as a first baseman probably magnified that. I think the back and oblique also were a factor. I don't think the oblique strains really fully heal until the off season. This could be a positive is they were fluke one time things. If they are going to be recurring problems due to his body breaking down due to age or the wear and tear of being catcher than we might see the Joe of old again. I think he is going to have a bounce back season and be a decent player, but I am afraid what will now be considered a good season for Joe would have been considered a mediocre or average season in the past. I think there were a number of unique factors that contributed to last year's season, but I think age and possible catcher wear-and-tear are always going to be a factor as well.
