Charlie Johnson continues to struggle as Minnesota's left guard and should be replaced in 2013.
As is the case with every NFL season, the Vikings should be well aware of where they need to improve in 2013.
There are some positions where massive changes must be made (wide receiver, left guard) and other positions where some change is needed (middle linebacker, safety).
The quarterback position needs to improve DRASTICALLY for Minnesota to be considered a serious contender in 2013, but Minnesota is unlikely to do anything too drastic to alter the position next season with Christian Ponder expected back as the starter for the 2013 season.
But at left guard, wide receiver, safety and middle linebacker Minnesota should seek additional personnel as the players filling those positions cannot be trusted (we're talking the safety opposite of Harrison Smith here).
Minnesota took its chances with Jasper Brinkley, Mistral Raymond/Jamarca Sanford, Jerome Simpson/Michael Jenkins/Devin Aromashodu and Charlie Johnson. But those players have shown they don't deserve to be starters on a contending team.
The Vikings may not take my advice and discard or bench all those players, but I guarantee that not every player in that group will be back for 2013.
