Yes and no.
2 of the big names are gone and Frank's not back until midseason. But the nucleus of the Sox rotation and 25 man roster save for ELo are still here. When Starks came aboard, wasn't it during the glorious age of Brent Barry & Kornel David? Hardly any remnants of the old Bulls-Knicks battles remained when Starks played for the Bulls.
Either way, if KW can swing a deal for Pierzynski, he should go for it.
