I am sorry but I have been a die hard fan since the Johnny U days back in Baltimore. I have never heard a professional athlete use the excuse that he hasn't learned the playbook yet. Running is a lot of instinct too and all Trent has to do is go home and look at the films. He runs into a pile up and never hits the hole. He is paid millions and its time he stepped up stopped using excuses about the playbook. I would hope the Colt's would have tested his intelligence before trading for him also and if he was that slow to learn they would have passed. Let Boom Herron get a chance. At least he hits the holes quickly and Bradshaw is a hard runner too. Trent run like a real professional running back or get out of the league because your playbook excuse is old.
