Eric Bitchoff, he was a great heel GM, and there wasn't anything wrong with him, the show wasn't broke so they shouldn't of tried fixing it, by getting rid of Bitchoff and bringing in others like Regal, Stephanie, Adamle, Vickie Guererro, Who only lasted a few months. Bitchoff was the best GM of Raw, and was GM longer than all the other GMs combined.
BQ: 1. The Rock
2. Hulk Hogan
3. Steve Austin
4. Barack Obama (will never happen though)
5. Kurt Angle (Also will never happen, as long as he is under contract with TNA)
I'm going to add one more to the list, I think Jim Cornette would also make a great host, plus he is no longer under contract with TNA, so it could happen, but unlikely too.
BQ2: The High Flyers: Evan Bourne, Billy Kidman, and AJ Styles.
