Florida gave up a recent former first rounder in Henrik Borgstrom to dump Brett Connolly's contract (2 x 3.5), so similar thing happened with the Caps including Richard Panik's contract (2 x 2.75). Depending on how you feel about Borgstrom, the deal could be viewed like:
Vrana + 2nd rounder for Mantha
Panik + 1st rounder to clear the cap space
Caps figure Vrana's impending new contract will be close to Mantha's AAV, so they bought some breathing space under the cap. It's to gauge this draft without everybody playing, but it had a bit of a 2012 vibe for me. 1st rounder sounds sexy, but sometimes it implies a higher upside than there really is. Caps pick will probably be 25-32.
