why? because roberts is a natural 2B & derosa is a natural utility man. He is like many spare parts in that the more he plays, the more he looks like the utility guy he is. there is a reason why he has never consistently held down a starting 2B job. Ala, Jerry Hairston, Todd Walker, Fontenot & theriot. these are solid players that are best suited as spare parts like a Tony Phillips. Great guys to have around.
