There is always room for optimism in sports- whether warranted, or completely unfounded, it's all about staying positive.
Take the 2008 Dolphins' team, for instance. After such an abysmal showing in 2007, having only won one game, a person could have argued that there was absolutely no cause to feel hopeful about what lay ahead.
That person would have been sorely mistaken, as the Dolphins' opponents from the 2008 season will surely tell.
While not as extreme, the disappointment over a sub-par performance in 2009 was palpable, and yet for many reasons, a few of which I will now outline, optimism should abound heading into 2010.
These are in no particular order, nor is the title meant to infer that there are only ten reasons for optimism.
