With Redskins training camp in progress down in Richmond, outside linebacker Ryan Kerrigan has clearly noticed the absence of star left tackle Trent Williams, who has yet to arrive at camp.

"Me, him (Williams) and (Nick) Sundberg have been here since I got here," Kerrigan told NBC Sports Washington Redskins Insider JP Finlay. "And it's just weird not having him here. I want him here, he's obviously an elite player and not only an elite player, he's the best. I can say with confidence he's the best in the league at left tackle. We want him and obviously, need him here."

Kerrigan was drafted in the first round of the 2011 NFL Draft by Washington out of Purdue, joining Williams, who was the team's first-round selection just a year prior, going fourth overall out of Oklahoma.

Kerrigan sides with Williams on his contractual holdout in its entirety. 

"From a contractual standpoint I 100-percent support him," Kerrigan said. "Whenever its the team or a coach making a business decision its a business decision, but when a player is doing it, he's being 'selfish'."

With Williams not in attendance at camp, the team signed veteran left tackle Corey Robinson this week and there are reports that the organization is still in talks to sign former Oakland Raider Donald Penn.
