Dan Uggla may not be a shoo-in at second base.
I can't think of why you give up much of anything to get one of those players and add it to THIS team.
Grafanino is a career .268 hitter. Yes, I know he batted .309 last year but he is hitting .100 this spring.
Relaford is a career .224 hitter and Perez is a career .244 hitter. Relaford and Perez can also play SS.
Still, I harken back to Wiggins quote: "if they are going to burn it down - let's burn it down all the way to the ground."
For my money, leave Uggla in at second and let's go with the kids.
