The Forsberg article indicates that it would cost $27 million to go down this road. In his thinking, this includes the 9 million to Green, plus the 4.5 million injury exception paid to whomever, and then the luxury tax adding another 9 plus 4.5 million in matching dollars -- totalling $27 Mil.
However, I have seen (I think from Roy) that the C's do not have to offer the 9 million (since the deal is void), but rather a qualifying offer of something like 5.9 million (if I am recalling correctly). This would produce an injury exception of about $3 million. In this scenario the total becomes 5.9 plus 3 times 2 (luxury tax), or a total of about $18 million.
Now $18 million sounds like a lot -- except that you've got to figure that it was in Wyc's plan to pay JG 9 Million anyway -- which meant a total of $18 million with luxury tax. In other words, if the C's apply for the injury exception based on a qualifying offer (about 6 million) and then turn around and use the $3 Million exception on another player, they will actually be exactly where they planned to be anyway -- NOT, as Forsfberg suggested -- $27 million down. In fact, even if they DID pay $9 Million and got a 4.5 exception, they'd be a total of $9 million over their planned expenses, not $27 million.
They really should have no good reason (of course, it's not my money) to not apply for the injury exception.
