I find it hilarious that many fans including many of our own who think Graham can't block. Yet, what they don't realize that Graham is replacing Luke Willson and Cooper Helfet.
Graham comes in at 6'7, 270... Bigger, stronger, and just as athletic as the 6'5, 255-260 Willson and double so over the 6'3, 240-245 Helfet. Both 2014 TEs arent really known for thier blocking prowess, yet the Seahawks still found a way to be a historical rushing team last year with those guys getting most of the snaps.
I think plug and play Graham is fitting and he'll do just fine, no one is asking him to be as good as Zach Miller. But just as good or a tad better than what the Seahawks had last year... And that certainly isnt the highest bar of blocking achievement.
