The Washington Capitals spent this entire season very close to the ceiling of the NHL's $56.7 million salary cap. There is no official word on what that number is going to be for next season, but it is safe to say there isn't likely to be another huge jump like the previous three offseasons.
Given that the Caps were one win from the NHL's final four, it does make some sense that players on the team were lobbying for GM George McPhee to bring everyone back for another go round. But that's just not likely to be financially possible, and if McPhee wants to make any out-of-house improvements, he's going to have to shed some high-priced guys.
If anyone didn't think the Caps need to unload a player or two (i.e. Jose Theodore or Michael Nylander), here's what the Caps' roster looks like right now (cap figures are for next season, or last season if said player is UFA/RFA):
