As for the Chiefs, they're not all that unusual to have one pick signed.
I'm not sure where Poe's contract status stands. But it's too early to be concerned about it. Last year, for example, Justin Houston was one of, if not the last draft pick to sign so that was a situation where you were concerned with what was going on. But Poe's not at the point yet where it's a problem.
