To be honest, I don't care who is GM. The WWE has not got enough stars that are "over" to fill a 2nd mainstream show that goes out live and keep them exclusive to 1 brand each.
I am not saying that WWE does not have talent - it does. But WWE has woefully underprepared for star creation in the past 10 years. I can think of a handful of superstars - CM PUNK, Daniel Bryan, The Shield - who have genuinely gotten over. Dolph Ziggler could have but he got trounced every time he looked like he would make it. AJ Styles may be close to it, but we are yet to see (he CAN EASILY BE) if WWE don't flunk it with him.
Who really cares who will be GM of Smackdown? More Shane is just more mcmahons on TV. It was old in 2001!!
