The Steelers have added seven undrafted rookie free agents at this point and there are some very interesting names among them.
Leading the group is Connecticut running back Andre Dixon, a powerful runner who replaced Donald Brown in 2009 and had just over 1,000 yard with 14 touchdowns.
Connecticut defensive end Lindsey Witten (6-4, 275), G-T Ciron Black (6-4, 327) and guard Dorian Brooks (6-2, 306) of James Madison also had draftable grades from most scouting services.
The Steelers also signed Miami (Fla.) center A.J. Trump (6-3, 310), Virginia Tech nose tackle Cordarrow Jackson (6-1, 305) and UTEP strong safety Da'mon Cromartie-Smith.
