IMO, the OL depth is by far the most tenuous situation. We will undoubtedly be relying on our offense to win games this year as nobody really has anything to go on regarding how our D will perform.
What we know is our offense has the ability to score more points than we're used to. With one or more of our starting OTs, we will enter the "Mike Adams Zone"...this is scary.
What we know for sure about our defense is that we have SOME average performers in positions which require better than average performers. Historically, we have had those better than average performers. This year is different. If we lose our starting ROLB, we actually IMPROVE at the position. If we lose Shazier, we might also improve over what he has put on tape so far by playing his replacement. If we lose a CB and are forced to play his back-up...we might actually get better. It won't be too hard to improve on the play of both of our Safeties performances from last year.
Obviously, Ben and his crew are paramount but we know we will have an immediate drop of talent without them. On this defense, nobody (short of Timmons, Heyward and Harrison) has put enough "gotta have that guy" performances on tape to be missed. Hell, we might even get a pleasant surprise. This D has it's work cut out for it but nobody knows what to expect from most of the starters, let alone their primary back-ups. The OL is a different story. We've seen what they can do when healthy and an injury to a critical position like LT will immediately put either a historically below-average performer in his place or a guy who was chasing the Taliban around the desert not so long ago at LT.
