I think the Smith injury is a good reminder that footballers should pretty much always strike while their metaphorical iron is hot for their careers, as much as it pains fans. For every player who stays another year and gets a better move there will be more who get injured or lose form - a few years back Minturn had serious interest from Middlesbrough, since then he's barely played a game for two years.
