That's a good summary.
Personally, Thursfield is a handy FB of the same type as McGuane & Moore. And a well structured team usually only needs two of these types.
I've never faulted his skills but I have also been disappointed that he has never developed the 'running on' side of his game and seemed merely content to be a 'stopper'.
McGuane has been the one to develop both the defensive & attacking sides of his game, and as such has kicked ahead of Thursfield.
And, as many have said, Rance, Astbury, Gourdis et al are younger players pushing for the same spot.
Certainly a good depth player at present but should have taken that extra step to be in the best 18.
But he's 24yo now.
Should have clicked by now.
