The Chiefs have made the improvement of the offensive line a top priority this off-season.  As the O-line gradually improved throughout 2009, there remains a few holes on that line that need to be filled. 

The Chiefs hope to have filled one of those holes last week with the signing of veteran Center and ex-Chief Casey Wiegmann last week. 

Another hole is speculated to be filled in the draft with the number five overall pick with the likes of Offensive Tackle Russell Okung out of Oklahoma State.

Today the Chiefs are reported to have ex-Colts guard Ryan Lilja in Kansas City to have a look at the guy the Chiefs originally drafted in 2004.

Lilja didn't make the roster in 2004, and was later signed by the Indianapolis Colts.  He is a five-year veteran with the Colts who started every game last year and started in Super Bowl XLI.

Lilja recently failed a physical before being cut by the Colts.  Lilja is injury prone and did sit out the 2008 season due to an injury.
