One of the RB's in front of him will probably get injured at some point this season. The team knows that. He will get his chance this year. Generally they don't have players inactive if they are are on the trading block.
Steelers need a reliable 3rd down back. He would be an upgrade over Samuels and he would be reunited with McFarland. Offer a 7th round pick. With the way Conners always gets hurt Ty would probably get plenty of playing time.
