Some of the casting ideas are just stupid. Tony Shalhoub was virtually unknown in the 1980s. Some of the other picks talk about how the actors' experiences helped make them great Doctors, disregarding the fact that some of the roles mentioned happened long after their supposed tenure on the imagined American show.
It's just a tongue in cheek article. Don't take it so seriously. And Tony Shalhoub had a few roles in the 80's before this supposed casting. Sort of like....Matt Smith.
