The impression I have of BDB is that he is good in the air in our box, but rarely competes well in the opposition box. I'm sorry if my impression is wrong (or perhaps not) but that's football. Btw do your well informed stats tell you how many headed goals he has scored for the Albion? He's one...
Still a young fella. He was 23 towards the end of this season (end of April), so perhaps only 20 first time he played in the top tier. Sharpened the edge in the second tier with goals and then a more productive season in div 1 as a 22 year old.
