A team's fortunes can often be severely altered by the injury or severe under-performance of just one player. When a team is littered with those types of players (see the New York Mets), a season can be over in just a few short months.
Coming into the 2011 season, every team expects to be better. If it didn't believe that, what's the point in even playing the games, besides the money of course?
Some of the aforementioned type of players have moved on to new teams. That doesn't mean they aren't expected to make a comeback in their new digs, however.
One player can make a huge difference, especially on teams that aren't stacked with talent from top to bottom.
Now who exactly are these players, and what is expected of them this season? You're just going to have to read on to find out.
