Tomlin or Grimm? Who is the Steelers' new head coach?

In the last 24 hours, some media outlets (like SI.com) have reported that Mike Tomlin is the Steelers' choice as new head coach. Meanwhile, the Pittsburgh Tribune-Review reported that Russ Grimm has been offered and accepted the job.

But the Steelers released a statement this morning: "At this point and time, the Steelers have not concluded a contract agreement with a new head coach, nor do we expect to do so today. There will be no other announcements from this office today."
