If Tyrod wins the QB competition it will be with his arm, not his legs. While I am sure the prospect of him running the option was on Roman and Rex's mind when they signed him, he will still have to make all the throws, as they say. And no one knows where EJ is at after being benched for 14 games but I can definitely see this competition coming down to Cassell and Taylor if the reports of EJ playing horribly in practice last year are true. Even Trent Edwards looked good in practice.
It will be interesting, to say the least.
