Salary cap: how do we get under?

Here's what I did earlier... keep in mind I didn't really do too much research into the specific numbers of it all and most of it is estimates, but I think this is a realistic scenario. I know I'll get automatic red thumbs for the cutting of Jenkins, trading of Ivory and Harper, etc., but we're all just spitballing right now as it is. Also some of the numbers are probably incorrect because I cannot read charts correctly.

Will Smith (9 million)
Jonathan Vilma (4.8 million)
David Thomas (1.5 million)
Will Herring (1.5 million)
