Seahawks newcomer Jimmy Graham has proven himself as a pass-catcher in the NFL. Now he must prove himself as a blocker on a team that features the ground game.

Teammate Michael Bennett remains unsure if that will happen. He once called Graham "one of the softest players" in the sport. He has not backed off that statement. He even added since Graham arrived that he would need to block more in Seattle.

No sweat, says Graham.

"Listen, man, I'm 270 pounds," he told 710 ESPN Seattle. "I can block anybody I want to. It's all about want-to. We'll see come this first Sunday."

Graham didn't block extensively with New Orleans. He was also not healthy. He dealt with injuries to his shoulder and foot in 2013 that hindered his ability in that area. But Pro Football Focus graded him middle-of-the-pack in blocking among tight ends in 2014.
