After watching Sam tonight I think your initial summary that a move to a smaller track may help him improve.
He seemed very awkward entering bend 3 tonight for some reason usually attacks the high line , his inconsistency is the only thing consistent with him the last few weeks but overall a fair result tonight both teams guilty of gifting points.
Will ten be enough I have a sneaky feeling it will be , on the Basso Brennan incident Tom was left with nowhere to go it was a hard move by Basso and a bit naughty as he glanced too see where Tom was coming from but as he was in front the only call the referee could make was to exclude Tom.
If Tom is in front of him on Thursday I think he will be as equally hard on him as he looked less than impressed when Basso passed whilst he was getting to his feet.
