He was captain of Walsall reserve team during the 2006–07 season. He was on the verge of the first team during this very season, however the management at Walsall believed that he lacked that competitive match experience which was needed to become a first-team regular.

However, during the start of the season he failed to do so spending a lot of time playing in the reserve side. February 2008, turned out to be a big month him following the sale of defensive colleague Scott Dann, who joined Coventry City towards the very end of the January transfer window. Despite the summer departure of fellow centre half Ian Roper, Smith remained as only the third choice centre half due to the arrival of Stephen Roberts from Doncaster Rovers.
