KW probably thinks the Sox are a legit contender and is banking his reputation on Maggs and Frank making quick comebacks in time for a possible September run. I'm pretty sure KW refuses to acknowledge the possible grim facts, figures Loaiza is more "run" ready than a minor leaguer if Maggs and Frank return in time, and, as always, KW is probably playing for now.
But playing for now with your two biggest bats out of the line-up for another month at the very least may have disastrous consequences on the White Sox Organization for years to come if Frank and Maggs cannot make an early September return AND be big contributors immediately.
