TheStreet's Action Alerts PLUS Portfolio Manager Jim Cramer said he would not be surprised if Allergan (AGN - Get Report) looked at buying Anacor (ANAC) before Pfizer (PFE - Get Report) decided to acquire the company for $5.2 billion, including debt. Cramer said, 'the area of atopic dermatitis is a crowded field. I think people have to recognize that Pfizer may have decided that we have to buy someone. This is a very unusual acquisition because Pfizer has been building up its cancer franchise.'
