What we learned during Omar Khan’s first draft as the Pittsburgh Steelers’ general manager was to expect the unexpected, whether that’s trading up, trading down or staying put. He did a little bit of it all last year, and with great success. Khan traded up in the first round, then traded back in the fourth, six months after pulling off a trade deadline deal that netted the 32nd pick, which turned out to be Joey Porter Jr. Though you never know exactly what the “Khan Artist” will do, you know what the Steelers want to be: a physical running team — an identity that was only solidified by the hiring of offensive coordinator Arthur Smith — with a defense that is stout against the run.
