1. Jose Reyes, SS: When healthy, Reyes is a legitimate star who contributes to his team via his bat, glove and speed. He has a good eye and gets on base at a high clip that also allows him to put that speed to greater use. But he was not often healthy the last few years, and the fact that his main issue is in his legs is a huge concern for any team thinking about giving him five years, even though at 28 he should be in his offensive prime.
