4 Areas San Francisco 49ers Must Address in Training Camp

Like every other upper-echelon team in the National Football League, the San Francisco 49ers have questionable areas that they must rectify in training camp. 

Whether it is finding a receiver to complement Anquan Boldin until Michael Crabtree returns or what has become a tangled mess in the secondary; San Francisco needs to find answers to a few questions over the next six weeks or so. 

Here, we focus on four areas that head coach Jim Harbaugh and Co. will be looking to shore up during the latter part of the summer months. 

At the very least, these are areas that remain unsettled at this early point in the evaluation process.
