Same can be said of EVERY team in the league for the most part. With few exceptions.To be fair, no one knew Byron would step up like he did, many pegged him as slot. Marco was also a surprise (as a rookie anyway). Alford playing well/not injured is also a big gamble. We just got lucky. We could have essily had an awful secondary, coverage wise.
Our pass rush is lacking now though, so our secondary has taken a hit. But it comes down to injuries in the end. What happens if Alford/Murphy goes down?
