I got no idea who thought of the X-Division, I could only guess Jeff Jarrett or Russo had the idea. But the TNA X-Division is composed of a mixture of WWE-ECW-WCW divisions of the Cruiserweights, Light Heavyweights & the Hardcore. The X-Division is like the former Cruiserweights of the WWE but they had the spotlight on them. They are unique in the way that they re-define the Cruiserweights and they put a more extreme aspect to it, also innovating moves and such. But lately, well I'd say it was right after Chris Sabin's last title reign in mid 2007 when the division started downwards. From what I remember, Sabin held the title for about 5, maybe 5 and a half months, then he dropped the title to Jay Lethal, who was doing that stupid Black Machismo angle. And Lethal held it for an astonishing 2 days...and dropped it to Samoa Joe, that's fine, since it does happen quite often now a days, like Triple H winning and losing the World Heavyweight or WWE title in the same night. But the problem is that Samoa Joe was still a rising star and was just beginning to main event the heavyweight division, what should've happened was that Samoa Joe should've dropped the title to Petey Williams or a rising TNA X-Division star, maybe Alex Shelly, but he dropped it to Kurt Angle in that "All or Nothing Match" where every TNA title was on the line. Angle won it, and the X-Division and the whole TNA show was featured around him. *Note: Kurt Angle looked like an idiot with all that gold, he had more gold on him that Goldust. Angle then dropped it to Sonjay Dutt or Jay Lethal, can't remember too well, but it was pretty much ever since, a lot of the TNA X-Division became heavyweight stars, or a lot have left, like Kazarian for a while though he was doing that Suicide character, Johnny Devine, Christopher Daniels, Elix Skipper, Sonjay Dutt, Low Ki/Kaval, and the biggest loss to date in my opinion, Petey Williams. But since Douglas Williams joined TNA, I find that the X-Division is only going to get better, especially with Amazing Red also in TNA now.
