Ivan Calderon (so slick)
Rafael Marquez (dominated 11
Vic Darchinyan (always comes to fight)
Roman Gonzalez (skills as well as as punch)
Juan Manuel Lopez (how good can this guy be?)

Just outside:

Fernando Montiel (awesome boxer, possibly better brawler)
Nate Campbell (will fight anyone)
Kendall Holt (can box as well as bang)
Chad Dawson (the future of 175?)
Joan Guzman (until his last escapade was top 5)
Ricardo Cordoba (most unappreciated at 122)
Herman Ngoudjo (arguably undefeated)
Roberto Vasquez (has the skills but needs to stay healthy)
Raytona Whitfield (could be a diamond in the rough)

One to watch:

Fernando Guerrero (can fight & brings a crowd)
