Spot on, Swiss!
It's all about getting best value for the funds available, and Wilder and Mitchell seem masterful at that. As Roy's 'View From' comments confirm, our signings tend to have an imperfection or two, which is why we can afford them. This works because we have a management team well versed in getting the best out of players and minimising any weaknesses, as they've proved with Clarke, Coutts, Freeman et al.
With the odd exception, e.g. Beattie, we've also been more successful, in recent times, finding young talent at modest prices (Ward, Murphy, Blackman, Adams, Basham etc.) than when we've spent big (Shelton, Davis, Henderson, Brayford etc.).
A very good window so far.
