Who can replace Buehrle?

A recent article featured on mlb.com, by Scott Merkin discusses what needs to be done in order to fill the hole in the White Sox rotation left by Mark Buehrle’s departure.  In the article titled “Peavy, Danks ready to fill in as White Sox ace” Merkin says that the White Sox have two viable options, Peavy and Danks.  Although I agree both individuals can deliver, I have my doubts.  Since joining the Sox, Peavy has had nothing but problems.  He seems to be on the disabled list more than he is on the active roster.  If Robin Ventura decides to have Peavy take over the number one slot in the pitching rotation, he is taking a large risk.  If Peavy is healthy it could be very beneficial to the White Sox, if he gets hurt and ends up on the disabled list again, the rotation could struggle.  Although Mark Buehrle was not the best pitcher in the league, he was always there and ready to play.  Don’t get me wrong, I do not have a bad word to say about Mark, considering he did pitch a no-hitter and a perfect game as a member of the White Sox.  This is just such a large role for one individual to fill and it should take a lot of time and consideration before someone is thrown into the spot.  Peavy and Danks both deserve the chance to prove themselves as the ace of the rotation, but what happens if they cannot deliver?
