Harris is not a step up , he is no better than Linus, it is a like for like, as you say Linus was improving and most fans thought if there were changes it wouldn't be him. So yes I do believe him.
So every fan on the terraces would want riders who have ridden for their team year in year out but now are off form and scoring poorly! No need to change he's a nice bloke who has been here years! I think you would find the terraces emptying very quickly, some fans go week in week out whatever but a lot wouldn't go if the team is bottom and doing badly.
It is fair to riders, sponsors and fans, who all know what happens if they perform below their level. It isn't about better off clubs either, i would think Harris is a cheap alternative to Sundstrom.
Proctor is easily as good as Klindt so could be as good, Leicester reserves are very poor, it is ok to say they need to do better but they don't have the ability. Bjerre looked unbeatable last week in the early races but after his fall he wasn't so good.
It wouldn't be allowed it is a bad comparison but any team like Real Madrid or Barcelona can buy any player but it is a completely different sport run a completely different way with squads.
A squad system could work in speedway if it was affordable.
