One of the best remaining free agent offensive linemen is now off the board. The Chiefs announced that they have signed guard Andrew Tiller. 
Tiller visited the Chiefs in late March and left without a deal, but the two sides circled back to each other roughly six weeks later. The Syracuse product started 14 games over the last two seasons for San Francisco and it’s a bit surprising that he had to wait until May to sign somewhere.
The Chiefs now have four true guards on the roster in Laurent Duvernay-Tardif, Zach Fulton, Parker Ehinger, and Tiller. In addition to them, they have a pair of guard/tackles in Jah Reid and Mike Person. The arrival of Tiller could displace Person, particularly if Tiller’s deal comes with a significant guarantee. Then again, since Tiller has signed so late in the offseason, he might not have much of a guarantee on his deal.
Tiller graded out as Pro Football Focus’ No. 43 ranked guard last season. He had nearly even marks for pass blocking and run blocking, according to PFF’s metrics.
