This is my first post so forgive any excesses.
The most influential player for Tampa Bay outcome in 2010 will be D Price. If he steps forward into the Kazmir slot, along with Shields and Garza, then you have a competitive team. If Davis improves and Niemann pitches at his 2009 level then you have a championship team.
There is enough hitting and defense, IMHO, and if the SP performs the BP will not be over exposed. It is essentially all on the starting pitching, especially these three.
