How did he go so badly off track?

Very strange.

Suppose it happens sometimes. I'm sure there has been plenty of potentially great fighters who haven't quite made it for one reason or another.

Strange indeed.

For his debut he was on the fight poster nearly as big as the headliner!

I guess he would have been a promoter's wet dream

I'm guessing he got a shock, the first loss was very unexpected.
He never regained his confidence or drive.

Pity, he'll be hard market if he continues.
