For me, Hickey is way better than Patterson. You could see it in the opening Ukraine game, I actually think it was a bit of a blessing that Patterson went off as we could definitely have lost a goal down that side. I've said it previously, Patterson reminds me of Hutton. Not a great footballer, but athletic and gives everything. Hickey can play football and is very aware of where he is on the pitch, hence a better defender. He'll play at a high level for a long time. Patterson not to be sniffed at of course and a fantastic backup to have. Hickey will move seamlessly to left back once Robertson retires and Ramsay moves into right back. Ramsay has the potential to be better than both if he fulfills it.
