Incredibly unrealistic to be honest. In my first season, as Somerset, I have the following team:
Trescothick, A Cook, Compton, Hildreth, Botha/Rahane, Kieswetter, Suppiah, Thomas, Swann, M Davies, Hussain.
With back-up players including Buttler, Dockrell, Willoughby, Trego, de Bruyn.etc.
Before hitting the T20 comp, Swann (despite missing 2 FC games to Tests) has over 100 wickets at approx. 10 each...
