Sometimes bad players can be called "clubhouse cancers" but I feel that is really unfair to cancer. Look at Leah Still in Cincinnati. Or the effect Chuck Pagano's cancer had in Indianapolis. All Red Sox fans are aware of Jon Lester's battle over cancer and that has been nothing but positive in Boston. So let's ditch the phrase "clubhouse cancer".
But what do you use instead to describe players like A-Rod and Ray Rice?
I suggest the phrase "contagious abortions". What do you think? A-Rod is sure to be nothing short of a contagious abortion this spring for the Yankees. Ray Rice returning to the Ravens is going to be nothing but a series of contagious abortions. I think it works.
It would also work as a fantasy football name.
