The kid had 16 penalties in his last year in college & brought that havoc with him last season to Dallas. Through four games, though, Tyler looks like a natural. He has been a big part of their success in the run game, particularly in wins over the Cincinnati & NY, when the Cowboys were often left-handed w/their rushing attack. In pass protection he's only allowed one sack in 255 snaps, according to Pro Football Focus.
Washington gave Smith & the Cowboys' offensive line some trouble. The offense averaged only 2.1 yards per carry & Smith has been called for three penalties in four starts. (so stop blaming McCarthy) But overall he has shown a blend of power & agility in space that's really impressive for a 21-year-old player.
