I don't know, he have always been a bit inconsistent, but this season he seems to be stuck in "first gear".
He did reasonably ok last season where he averaged on about 9/meeting so I don't think its a silencer issue.
If i would guess, i would say that its "brain ghosts (hjärnspöken)" which means that its in his head and not an outside/bike problem.
I remember Rory Schlein when he rode for Smederna. During first season he rode really managing some 8-9p/meeting as a heat leader.
but then the next season he was awful hardly scoring anything except as a reserve for some meetings.
I do hope that Jonas can get back on track, Swedish speedway cannot afford to loose him into retirement.
