Common burdock and cocklebur are not the same.  Cocklebur is an annual plant.  Burdock is a biennial, and the 2nd year growth in particular will have a massive root.   The growth habits look very different as well.  Seed pods are different - burdock will have a round pod; cocklebur will have an oval seedpod.  That to me would be the telling difference.  In the OP pics, it is a bit blurry to be sure.  However, based on the growth habit, I believe it is cocklebur, and not burdock.

Cocklebur -  notice the oval shape seeds in the pics

Burdock - notice the rosette appearance of the bottom leaves.

Burdock - scroll down to 5th pic.  Notice the growth appearance of the plant.  That to me is what burdock looks like. I don't see this in the OP pics.
