The problem is that none of the McCabe fan club can provide a cogent argument in his favour IF he does what he's done time and time again and fails to stump up the readies for Tufty. We can all bang on until the cows come home about how we'd run the club, but it means precisely fúck all, and we realise that (regardless of how certain people like to make ridiculous straw man arguments about what we apparently want the club to do).
I, like you, would love to be proved wrong this time. We have a very good chance of achieving promotion. No one at all, as far as I can see, is advocating 'splashing the cash like Wendy did', to use Aya's phrasing. What we do want is for Tufty to be given whatever he thinks is appropriate to push on. If they don't trust him to spend the money judiciously (and I fail to see how anyone could not trust him, given the amazing job he's done for us thus far), they shouldn't have taken him on in the first place.
