Boston College
On December 12, 2007, Bicknell was hired by Texas Tech to serve as their offensive line coach. However, when Boston College offensive line coach Jim Turner resigned that August, Bicknell left the Red Raiders to rejoin BC.
In 2007, BC's offensive line ranked first in the ACC in sacks against, allowing just 22 sacks all season. His offensive line also paved the way for an ACC-leading 5,951 yards of total offense and a record breaking season by quarterback Matt Ryan. Bicknell also oversaw the development of Anthony Castonzo, the first true freshman to start on the BC offensive line since 1997 and a member of the All-ACC freshman team.
