Of the Buffalo Bills' four tight ends, the one who gets talked about the least is Lee Smith.
That's because he has been quietly doing his grunt job all year.
Smith has three catches for 47 yards without a touchdown. But his primary job isn't to make downfield plays; it's to get in the defense's way.
ProFootballFocus.com rates Smith the NFL's best pass-blocking tight end.
Among tight ends who've played at least 25 percent of their teams' snaps, Smith is the only one not to have allowed a sack, hit or pressure. The Bills have used him on 98 pass plays and kept him in to block on 39 percent of them.
Smith has been used as a run blocker on 212 snaps, PFF's data shows.
PFF's charts also show why Scott Chandler, the Bills' second-leading receiver, rarely is asked to protect the quarterback.
He has played 416 snaps, but only 25 of them in a pass-blocking role. He has allowed a sack and three pressures.
