I've seen Mathers play some great games this year, but yes he has made mistakes. His consistency is a concern (especially as a fullback), but I also feel that he is a very talented player and hopefully he will go well for us.
I would have Hodgson over him personally, but on the other hand I feel that Mathers could be the best full back we've had in some time.
My concern is that he gets a bad start, his confidence goes and the fans then get on his back. If that happens then there could be no coming back for him, so hopefully he will bring the confidence he will have gained from his great season with Wire into his role with us.
Time will tell.
