When you consider that until last season we had 6 years of brutally bad centre halves (it pains me to even think of some of them and of the debates about whether rotten centre half A was marginally better or worse than rotten centre half B), to be where we are now with Helander, Goldson, Katic and Edmundson (and some promise in the likes of Mayo in the younger ranks) is fantastic. Throw in that we have a very good goalkeeper, a fantastic right back, good cover at right back and left back and we are in a very good place. Barisic clicking at left back is the only question mark; and even there the mood music seems a bit more promising now that he has had a good, injury free pre-season.
All the good Rangers teams have been built on a rock solid defence. It feels like that is what we should have again this season.
