Honestly what the UFC should do to refresh the heavyweight division is this:
First offer Sergei Kharitonov a contract to switch from Pride.
Go to the Russian and Brazilian top teams and get a heavyweight from each, cause they have to have a heavyweight that arent signed yet.
Get another heavyweight from Chute Boxe, if they have one.
Persue Jerome LeBanner and/or another heavy from K1 that is trying to make the switch from kickboxing to MMA. Such as Aleksey Ignashov.
And they have to start penalizeing for inactivity, like two warning and then a point. The UFC is so geared towards lay and pray victories and counter-fighting.
Bottom line is that they have to do something.
