which heavyweight on the comeback has the best chance of success?

[joe strong]

Rahman,tua,Briggs,gomez,grant,kirk Johnson have all started comebacks.which one has the best chance of making a splash in the title picture? Tua is my choice because he's beaten ahunanya & cameron compared to the rest of guys the others have fought.I think all these guys could beat chagaev or meehan

add liakhovich to the comeback list.
