I seem to remember him being taken under Gary Havelock's wing when he was a real hot prospect at Coventry, I'm not quite sure where it all went wrong for him Speedway wise. Personally, I think as he's not currently banned from speedway, as some riders are, he should be free to ride, if he can find a club that'll have him, I think he maybe needs somebody to take him under their wing again or a chaperone type person a bit like Glenn Roeder with Gazza when he went to Italy, just to keep him on the straight and narrow.
Many "famous" people have been to prison and then gone on to make a success of their lives, Gino di Campo also broke into somebody's home and look at him now. Sometimes prison is the wake up call for people to turn their lives around.
Personally, I'm with you and wouldn't touch him with a barge pole but that's just me, if I were a promoter at Plymouth or somewhere I may be thinking differently.
