Washington-Las Vegas is a much better series than it would have been with Tampa.
I think Vegas will win in 6. Incredible story.
I might have agreed with you about Vegas until seeing the last two games of the Washington series. Now I'm not so sure. They dominated a Tampa Bay team that seemed like it was clearly the best in the Eastern Conference coming into these playoffs. TB's only major flaw was having a broken-down old jalopy like Dan Girardi playing 20+ minutes a game on defense. LOL.
I haven't seen much of Vegas, though -- so I may be underestimating them here.
