He had the tools be a half decent contender. Decent dig and fundamentals Lewis beats him 99 times out of 100 luckily for Hasbeen Rahman he got his 1 out of a 100 moment in in the first fight.
Clear #2 behind Ingo. He lost focus when he took on Lewis, who was a hot-and-cold contender who just happened to be "on" that night. Real Tokyo Douglas situation. It can happen to any ATG.
