A few of the Colgan guys especially have been busted going from a prop to a jet. It will not look good when they apply to a jet carrier and their only failure was them trying to transition to a jet for the first time.

We all know that a transition to a jet is a learning curve and has its differences but the folks I know personally who have failed are great folks and skilled aviators. Something has not added up when listening to the breakdown of their training. While different, the transition should not present much difficulty to the folks who put the effort in.
