It was a joke - as everyone has noted, we need more depth at CB. Although I was thinking of Long's transition many years ago. Barlow does have the height, athleticism and physicality to at least make you wonder if it had ever been considered.
I, too, don't mind having him on the team as the 4th option up front. You know you'll get an honest effort - and he'll bungle in a handful of goals by season's end.
