This would be really interesting. If Strikeforce got their hands on Barnett they would have a great Hw devision.
Fedor
Barnett
Werdum
Overeem
Big Foot
Rogers
Lashley
Sefo
Roger Gracie (I think is under contract)
Monson (Rumoured)
I dont expect much from 47 year old Herschel Walker seeing as he is a very small Heavy and at his age he better make a flying start!
They also have King Mo who said he could fight at heavy and will have fought at heavy for his last 2 fights
Andrei Arlovski anad Tim Sylvia are free agents and Tim is competing in Dream so theres every chance we will see him in Strikeforce.
Also there Ironhead who fight for Dream again with the alliance they could have him compete in the states. Their heavyweight devision really will be strong if they get Barnett and a few of the free agents. With Hendo under contract it seems Strikeforce are getting stronger and stronger.
