The Giants added two front-line starting pitchers in free agency.
Their lineup is considered one of the best in baseball.
What about the bullpen?
"That's the No. 1 question.," Mike Krukow said on KNBR 680 on Monday morning. "You lose a component like Jeremy Affeldt, who has been an amazing contributor to that bullpen for the longest time ... a guy like that is difficult to replace and I'm anxious to see how they're gonna do it."
From 2009 to 2014, Affeldt racked up a 2.76 ERA over 362 appearances.
