I don't understand why some people are questioning why Florida made this deal.
They're just outside the playoffs, well within striking distance. They have 2 metric tons of youth, so it's not like they need all of their draft picks. Jagr is the veteran leader at the deadline teams with youthful cores always bring in. Plus he can play on the top 2 lines and can still score.
From everything I've heard about Jags since he came back from the KHL is how he sets an awesome example for the younger players. This sounds like a very good player for Florida to bring in to make their push.
