Personally I'm goign with Swooper. Realistic in the sense he'l; be reasonably cheap, still loves the club so would be willing to take on the challenge and has a track record for turning struggling clubs around. The money we save on appointing Swooper could then be used on hiring top assistants which one of could take over after say 3 years. If we had great assistants who were up with the modern game that could help Northey out, given he's been out of AFL awhile, although still coaching in Ballarat.
The coaches I've listed are probably the only ones potentially available IMO. Can't see a Clarkson or Worsfold leaving their clubs to come and coach us.
Would love to see what other people think is the most realistic option.
