The only sure thing is Florida will be the top seed in the East and play WC2 which could be Washington, Pittsburgh, or the Bruins.
The Bruins can certainly catch Tampa and wind up as A3 which would meet A2 Toronto.
Most likely the Bruins finish as WC1 by finishing as A4 and play the Metro winner which suddenly is a battle between Carolina and the Rangers.
The reality is this may well go to the final night on April 29th
