Believeit is right. NOBODY runs on `64 Roseboro. If you want to shut down the other team, nobody gets lower SBA than Roseboro, though he may not have the chance to throw too many guys out -- and his low PA requires a platoon.
I've never been tempted by Piazza, but I've tried Rudy York a few times because he's such a cheap source of homers. I didn't like the results at all. He delivered as promised offensively, but other teams in $80 MM OL ran wild on him. Back to A+ arms, though not always A+++.
