Do Dhoni's remarks indicate an underlying apprehension?

I might be getting a bit too suspicious here but the fact is that on the eve of their departure to the West Indies for the forthcoming World Cup 2010, the Indian captain did seem very mindful of the fact that most of his team members had participated in the very demanding format of the IPL3 and that this Indian squad certainly wasn't the freshest one in terms of the participating teams at the Caribbean event. What makes me believe this is that MSD himself isn't the greatest of supporters for the theory of playing non-stop cricket.

If you look at this captaincy record, there have been instances where MSD had himself sought the permission of the BCCI to take a rest between two series-something that no other Indian captain has dared to do in the past. Further, Dhoni himself has a very suscpet back that has been troubling him for the last two seasons. Further, to maintain the balance in the team, he cannot risk taking upon another specialist keeper to resolve this issue. So, there is basically no way in which Dhoni can reduce his workload and further, some critical teammates like Ashish Nehra and Yuvraj Singh are still recuperating and are yet to hit peak fitness.

In the background of such issues, it was strange to see that Dhoni went on to explain that his team was 'fresh' at the press conference held on the eve of the team's departure and went on to explain this without much prompting from the surrounding media persons? Is he being wary of something that is bothering the team management?
