  "With a career line of .235/.334/.405, Johnson is pretty much the definition of a replacement level player. And with Paul Konerko and Adam Dunn inhabiting the roster, barring significant injuries, Johnson is unlikely to see the major league roster."

  "A limited player defensively, Johnson basically just gives the White Sox another option for 1B/DH just in case Adam Dunn totally falters again. He got some attention in 2010 for hitting .303/.430/.624 with 30 homers in 98 games with Triple-A Durham, but he fell back to Earth while hitting .273/.382/.459 with 13 homers in 93 games with Durham in 2011."

WAR's toll on the White Sox - South Side Sox
"In the Jerry Manuel years, the negative-WAR players were the kind of players you'd expect to not contribute all that much -- backup catchers, utility players and rookies. You also see a couple of players who were thrust into positions they weren't cut out for -- Perez and Borchard had to try to replace Magglio Ordonez after his knee injury in 2004, and Daubach played more first base than expected as Paul Konerko contemplated his entire hitting approach. Really, that Konerko death spiral is the only occurrence that qualifies as a complete letdown."
