Sami The Black-smith has unlimited potential! If he brings his 'back' in, then who knows what is possible.
So much hype for Heath, and yes he is a threat, but Sami, in my opinion, is the man!
I dont think Sami will be doing 'the damage' right now. He needs to deal with the PDI issues etc.
Sami needs a couple more years to develop muscle-maturity. Then i believe, the sky is the limit for this 'diamond in the rough'.
Keep training hard Sami, you are Olympia material!
