I'll be homerific and say that if Hutchinson is the #1 guard in the NFC (and I think he probably is), then Randy Thomas was #2. At least last year.
It's not just being a homer. I was going to mention him when I saw this thread early today. Thomas is playing at an extremely high level and not getting his props. They should consider moving him to the left side and letting him and Samuels plow the way for Portis. I know that's the idea with Jansen on the right side, but I like the way Samuels run blocks. Samuels is in the pro-bowl, Jansen gets all the praise, but Thomas is the best OL in DC.
