Jacobs on the hot seat?

[Paintrain]

While I expect Jacobs to make the team, my concerns about his toughness persist. I think he has a little bit of bitch in him.. I don't know that he has what it takes to make it in the NFL.. He seems great vs. air, but I don't think that when the live bullets start flying he is able to step it up.. Other than his rookie year with the internal injury that his injuries have been to the point that he was inactive.. Has he had any surgeries in his career or have they all been sprains and strains? He needs to know the difference between being hurt and being injured.
