It's possible that something has been said or written that I was just unaware of. That said, I read and research a lot in terms of baseball. I took the time last night to search for anything written about bad team chemistry or poor management leading to failure to perform on the field for the Nats. There were plenty of things written in hindsight, but in terms of preseason predictions, I came up with zilch. You would think that if this were the opinion of many analysts, I would be able to find something.
What I found was that, not only were the Nationals heavily favored to win their division, but of all the sites I looked at, and it was quite numerous, the vote was unanimous. Not only that, but in most cases, the Nats were predicted to win their division by a fair amount. There were some concerns about injuries, but not enough to dampen anyone's predictions. And not one word about bad chemistry. I can provide links if you'd like.
As far as the quotes from your post, do you realize that your "analyst" is a 14 year old boy who wrote those things in his blog? Is that the best you could do?
It's quite possible that someone on the radio discussed it last year. But here is what you wrote:
Their failure to perform on the field has been predicted by many analysts who recognized the poor team chemistry and bad management.
That is a very misleading statement, at best.
