Very similar to Tim Stone at Newport, done a fantastic job to bring the sport back and put his money where his mouth was. Stoney wasn't everyone's cup of tea (myself included) but put his life into the place. Granted, Len didn't let things get as bad as Stoney did at Newport but you'll see what I mean. Stoney brought the sport back and built it up very high very fast, and the memories he brought to Newport fans will never be forgotten. Post 2003, Newport fans prayed Stoney would sell up and move over for someone else and the family everyone wanted to take over eventually did and we all seen what happened pretty quickly once they did.
Len brought speedway back to Rye when nobody else could or would and within a couple of seasons they were a Premier League mega force. The 05 and 07 teams Len built were superb and you'd actually enjoy and admire seeing them come to Newport, especially Robbo who was pure box office.
The sport could certainly do with a lot more promoters in the mold of Len Silver now that's for sure.
