Good exercise. I think with RTB as coach you have to think in terms of the type of players he favors - hard working role players. For me that puts Gresham and Billings firmly on the chopping board with the added bonus that there is probably some limited trade value attached to them.
There will be the usual culls of players just not expected to make it or have gone past their use by date - maybe MacKezie, Highmore, Connolly.
I don't think its that he favours hard working role players, its more along the lines of , "If you are an ordinary player, i might give you a role to play within your abilities, and you'd better work hard at it ". He really likes his big stars with lots of ability but no team has 22 superstars.
