What is going on with Penske and Ganassi in Indycar?

Penske Racing and Ganassi Racing have been THE 2 powerhouse teams for quite a while in Indycar racing, but both of these teams have been off the pace this season. Allmendinger outqualified the 2 full time Penske drivers with a best of 5th at Indy. Ganassi's best driver is currently 16th. Not exactly the front row spots these two teams are used to. Best part out of all this is the door being opened for other drivers to step up and run well - like Takuma Sato and Ed Carpenter, this year's 500 pole sitter. Will Penske get their crap together and possibly take another 500 victory in 2013, or will they continue to be mediocre?
