Trubisky is still pretending his legs don't work I see. Even before the injury, he wasn't running much. Not since the Minnesota game where he got injured (reminds me of Grossman would use to run, then tore his ACL and then pretended he was a pocket passer). The numbers indicate that too.
This was a guy who was rushing for 30+ yards 5 different times last year (6 counting the Minnesota game where he got injured). Same with the attempts. He has not had more than 30+ rush yards or 5+ attempts since then.
