You gotta go with Giles and Chavez. Piazza is in serious decline and nobody seems to want to face it. If you don't trade him now, it may be too late to get value for him. Giles and Thome are about even overall, Thome will hit a few more HR's, Giles will have a better avg...similar runs and rbi's. Chavez is a stud that will have a huge year, maybe 40 HR's and 120 rbi. If not this year, then very soon. He'll outproduce Piazza this year and every year from now on.
