Apologies.......but my argument for the first season at Withdean still has its merits. Of course you will factor in the return to Sussex, but likewise your example of the last year at the Goldstone hardly promised "hope for the future".
We did not spend money in the first season at the Withdean, so I think the decent crowds were a novelty factor to be honest.
The next season we gambled on BZ and it came off, he was not a 'name' player, so would not have attracted fans on the basis of your argument.
