They're going to have to move out the middle class on their team. They have $5.3 million in cap space with only 15 players signed. Notable RFA's are Sergachev, Cirelli and Cernak.
The Tampa offseason will be similar to the 2010 Blackhawks. That Chicago team won the Cup then had to trade Versteeg, Byfuglien and Andrew Ladd due to the salary cap. They took a short term step back (finished 8th in the West in 2011) but obviously went on to win 2 more Cup's. Tampa's going to have to do the same thing- trade out the middle class. They have $5 million in cap space with only 15 players signed, and notable RFA's Sergachev, Cernak and Cirelli. They'll have to move 2 or 3 of the Killorn, Johnson, Gourde, Palat group. They all make between $4.5 and $5.3 million. They are going to have to fill in the gaps with the Schenn's, Bogosian's, etc. of the world and ELC's. The good news for them is those 4 players should all have real value so they aren't going to get nothing in return for them. They traded a lot of futures for Coleman and Goodrow (2 1sts and Nolan Foote) but I'd anticipate they could recoup some of those assets in these cap clearing deals.
FWIW, I think the Vasilevsky deal was a dumb one.
