If Guerin made half of his $6.7 million salary, perhaps the Stars wouldn't be seriously considering a buyout by Friday. Instead, in the salary-cap era, they could save $4.5 million toward the $44 million cap - and they currently have only about $8 million left with 15 players under contract and free agency ahead. The decision facing team owner Tom Hicks and general manager Doug Armstrong - if they haven't already made it - seems to be all about the numbers. For instance, could they even theoretically keep Guerin and sign free-agent center Jason Arnott and either defenseman Willie Mitchell or Jon Klemm? "It just becomes a math equation then," Armstrong said. "Look at your roster and add that number. You really do have to rob Peter to pay Paul in a cap system to get it all in there."
