Moats had a visit scheduled with the Steelers on Monday, so it appears as though a deal came together fairly quickly.
Moats, 26, was a sixth-round pick of the Bills back in 2010 and spent the past four years in Buffalo.
Last season, Moats appeared in all 16 games for the Bills and totaled 54 tackles. Pro Football Focus had him rated as the No. 12 inside back in the league last year.
We had him listed as the No. 12 best available player in our Top 50 Free Agents list.
