The main qualities i'd be looking for in a CB would be defensive abilities somewhat in advance of blancmange. I don't care ewhere they're from.
Maybe British players do develop playing in a more suitable style for the Spl. Mcdonald has been better than Jensen when he's come in, but it's marginal.
We've had four Scots starting regularly recently. Which i don't think is unusually low for the league.
It was a lazy trollish swipe by Tam, but it got some bites, so fair play.
