Don't forget about Brandon Kintzler.
He was the most high-profile of the Cubs' midseason bullpen additions last summer, but struggled out of the gate and faded into the background while less-heralded veterans Jesse Chavez and Jorge De La Rosa emerged as diamonds in the rough.
Chavez and De La Rosa are gone, but Kintzler remains a part of a Cubs bullpen that is firmly under the microscope this spring.
His introduction to the Cubs was forgettable (7.00 ERA, 2.00 WHIP in 25 games) but he conceded he put too much pressure on himself and relished the opportunity to hit the reset button this winter.
