Caps in seven because Caps. I think their typical level of play plus some urgency ought to be sufficient. It's not like Philadelphia is tremendously deep or overly impressive on the back-end overall.
I don't think the Caps are true contenders until they collectively display consistent mental engagement and crispness but that is something of a process. I'm skeptical they'll be overly quick learners given their history and apparent foundation or that they'll get on a tremendous roll ultimately but they should be able to handle the first round at least. If not, man, I'd be pretty tempted to blow it the hell up.
