Here's the overall quote:
Martin was the other veteran on the team. I never got a douchey vibe from him though. Bautista was Bautista but he wasn't there last year so I wonder how much he played into those comments.
Donaldson kind of seems like the prime suspect. I remember when he went on his "this isn't the try league, it's the get it done league" rant. Most fans loved it but as a teammate that's not something you exactly want to hear. Tulo is another prime suspect. Those two getting hurt and losing a bunch two years in a row is also going to affect how one views them as clubhouse leaders too.
Regardless, it doesn't seem like it was an epic meltdown in leadership from anyone, just maybe some personalities butting heads a tad after two frustrating seasons.
