One thing about on-field reporters is that they have a earphone on that is linked to a producer. Often, an on-field reporter that is not your seasoned veteran on-field person will take the lead from the producer. You'll get stuff like "Ask him about..." and the reporter will usually comply. Rosenthal is not an on-field reporter, he's a journalist (or should be), so he got hung up in the moment and just may of listened to his producer instead of going ahead and doing the job of interviewing a guy as he would normally do.
Ken Rosenthal is not your usual on-field type, so he gets a bit of reprieve but overall whoever thought it was good television to hit Lidge with the "given your history..." question was just looking for the next Pete Rose moment. That's television.
