The 2009 season will be an important one for the Indianapolis Colts’ offensive tackles, with a lot of focus on the left side of the line and the development of third-year veteran Tony Ugoh.

Can Ugoh fulfill the potential that made him a second-round selection in the 2007 NFL Draft?

Can nine-year veteran RT Ryan Diem remain healthy and play 16 games for a second consecutive year?

Will veteran Charlie Johnson be the backup tackle, or will he play guard as he did last season?

And just how deep will the Colts go at the position?

These are the questions facing the position entering training camp. In the fifth of a 2009 pre-training camp position-by-position series running late this month and early next month on Examiner.com, Indy Football Report Editor John Oehser addresses those questions and more.
