Steelers add O-line coach

After losing several coaches in the past week, the Pittsburgh Steelers made an addition for 2010 by hiring Sean Kugler to be their offensive line coach.

Kugler was the former offensive line coach of the Buffalo Bills. You can read more about Kugler and his stint in Buffalo here in Tim Graham's AFC East blog.

Pittsburgh's offensive line has been a hot topic of discussion the past several seasons. Steelers quarterback Ben Roethlisberger likes to extend plays, which makes him very hard to block for and results in a high number of sacks.

Kugler will replace Larry Zierlein next season. It will be interesting to see what adjustments Kugler has in mind to fix Pittsburgh's much-maligned unit.
