Ariad Hires Hugh Cole, Shire Pharmaceuticals M&A Guy. Any guesses why??

Ok, clever Ariad investor, you read Cole's bio on the Ariad web site. Very good. But did you check his FORMER employer's web site to see what Cole was up to at Shire, M&A wise, during his seven year tenure? Fourteen (yup, 14) acquisitions and/or major partnerships during his reign. But don't believe me, count 'em yourself.

So, why did Ariad hire M&A guru Hugh Cole about 30 days after Activist Investor Denner signs on?  

You tell me.
