With cup runs and a long slog of a season, I think Faddy could prove to be a decent signing coming off the bench and maybe even starting the odd game.
For a decent promotion push you need a deep squad, even though he is 34, if the hunger is there then he'll add something to the season.
Obviously as others have pointed out, Naysmith has seen enough of him to make the call, so you would assume fitness is there.
