The San Francisco 49ers are less than a month from their first practice of 2015 training camp. Once camp gets going, there will be daily media reports leading up to the preseason opener on August 15. That time will give us a better grasp on the depth chart, and which players have climbed onto the bubble.
As we approach training camp, we'll be assessing the roster in several ways. We'll start with this bubble watch post. We'll go position-by-position, and break down whether players are locks, strong bubble, weak bubble and longshots. The discussion for each article will not follow a specific format, but rather will focus on the more interesting aspects of the particular roster competition.
