You say that but the lack of a Cruiserweight Division hasn't prevented Kidd and Bourne from doing well.
I'd love to see the WWE bring back the "Light Heavyweight" Title. Like the world championship for smaller guys. It could really be worth something if done correctly. Make it tri-branded. Imagine the possibilities:
Evan Bourne
Yoshi Tatsu
Tyson Kidd
Gregory Helms
Jimmy Wang Yang
Jamie Noble
Chavo Guerrero
Primo
The Brian Kendrick
Kung Fu Naki
Bring in a few lightweight upcomers from developmental and we're all set. It would be awesome an relatively easy to pull off.
