I'm not quite sure what he adds. I wouldn't say he impresses at anything specifically but he's definitely contributing. a good job too as if he, Sinnott and Bowerman were continuing their earlier output we'd be in trouble.
I'm impressed that he seems to have had the character to accept he was playing sh*te, tell LS as such and buckle down and improve though.
Also for the record, Sinnott finding right back a position that suits him a little better (as long as not faced with a real quality winger) and did well on Saturday I thought. Yes gave the ball away for the goal but I've seen plenty of full backs hash clearances with their wrong foot.
Both players a work in progress but at least progress bring made.
