I know it's more than a tad revolutionary but this is what I would do .............

1. Decide how we are going to play, which system. Making sure that it is both successful and entertaining
2. Which players do we have that either don't fit that system and/or have passed their sell by date. Get rid
3. Which players do we need to play that system? Go out and get them.

Too Utopian? Probably but I have seen too much of this defend the last 30 and then hope for a counter. I want to see us defend when necessary and attack the rest (most) of the time.
A mix between Mac's gung ho and GR's safety first approach.
