I doubt Clemens would get $20 million. Probably 10, and he's worth every penny. Like 26 to 6 said, if all he cared about was money, he'd sign with whomever wrote the biggest paycheck.
That was four years ago? Point is, that whether you like Clemens or not, he would be a HUGE addition to the Red Sox. No way could anyone touch a front three of Schilling, Beckett, and Clemens.
