To some degree, I think that this is basically remembering the good old days as being better than they actually were. Whenever a thread is started regarding the prestige of mid-card titles in the WWE, the reigns of a certain few are always brought up like Randy Savage, The Ultimate Warrior, Bret Hart & Mr. Perfect. You know, there's always mention of guys that went on to bigger and better things, guys that went on to be main eventers or "should have been" main eventers. But, lengthy runs from guys like Ken Patera, Tito Santana, Greg Valentine & Shelton Benjamin are rarely ever brought up when it comes to talking about IC title prestige and credibility. Forgettable runs from the likes of The Mountie, Bob Holly, Jeff Jarrett, Ahmed Johnson, Mark Mero, Ken Shamrock, Val Venis, Road Dogg, The Godfather and many others are also often left out when it comes to talking about prestige.
The IC title has had it's share of lackluster reigns in this decade, but that's nothing new. There have been times all throughout the history of the title, even back in the "good old days" of the Attitude & Hogan Eras, in which the title has been held by wrestlers that have been forgettable and/or mediocre. Or, it's even been held by pretty good wrestlers that just generally haven't received the level of notability or fame that guys like Bret Hart or The Ultimate Warrior have.
For many of us, the IC title held by Dolph Ziggler or Rey Mysterio or whoever will never be as prestigious as the time Randy Savage held it because many of us grew up watching Randy Savage. Not that Savage wasn't great, but guys like Savage will always hold a special place in the nostalgic hearts of a lot of fans as his matches and feuds during that time generated great memories for us as kids that we still treasure today. Overall, I think Ziggler has done a good job as IC champ so far. He's certainly defended the title quite a bit in a short span of time and, if I'm not mistaken, he has a title defense on tonight's episode of SmackDown!.
