Pittsburgh's rivals in Baltimore are the most surprisingly fascinating team. Their games are all close chess matches and they are so clearly building toward something greater. Like Bill Belichick, John Harbaugh is using the early part of the season to figure out what he has. He's learned that Terrance West is worth making his starting running back. He's learned that Dennis Pitta's comeback is real, that Brandon Williams and Timmy Jernigan are now among the best defensive interior duos in football, and that safety Eric Weddle is a problem solver. Harbaugh has learned Steve Smith still has incredible juice for his age and that Mike Wallace fits quite well as a role player, thank you. When Wallace is catching slants on third-and-long, you know this coaching staff is doing something right.
