Water to wine is one thing. Water to smoothies - that's something else entirely.
With the Phillies in the tank, the Sixers angling for a lottery pick and the Flyers treading water, it's no surprise fans are ready to put their heart and soul into backing this squad, Vick and all. At least no one has referred to Chip's crew as the "dream team"... yet.
