With all respect, if Overeem doesn't win in the first round, does he deserve to be the champion? Surely if he loses to Werdum in an MMA fight in Strikeforce, he should lose the Strikeforce Heavyweight title. If Werdum should lose in the semi-final of the tournament, then whoever beats him deserves the belt.
In my humble opinion, if Overeem is in the tournament, he should be defending the title. Otherwise take him out of the tournament and have him face the eventual winner.
If you take the fights as being individual unto themselves then you would expect Overeem to be defending his title in a fight against Werdum anyway, so why not have the title on the line in that fight? If Alistair is the better fighter he will beat Werdum. If he loses and keeps his belt, Strikeforce have just put themselves up poop creek without a paddle. Just because the fight is being labelled as being part of a tournament, it doesn't mean that the title shouldn't be on the line.
Say Barnett goes on to win the tournament, what does it matter? He isn't going to be the champion, so by definition he isn't the best. The only winner in this tournament is going to be Alistair Overeem, even if he loses he will still be the champion. I don't understand Strikeforce's logic on this one.
