"Brent's an outstanding blocker," Kelly said, via NJ.com. "I think he may be the best blocking tight end in the league."
Of the 61 tight ends ranked by Pro Football Focus, Celek is fourth in blocking.
"Probably not, to be honest," Ertz said, of a hypothetical role for Graham. "I don't want to take anything away from Jimmy, but the things I've seen, he is more of a pass-catching tight end. In this offense we are a run-first team and we don't sub because we go at (a fast pace)."
Kelly is one of the brightest offensive minds in the game. There's little question he would find a way to highlight Graham's mismatch potential if given the opportunity.
Still, the larger point stands that different schemes require different traits, especially in today's era of specialization and multiple personnel groupings.
