Evaluation of this team, as well the individuals that make up the team, falls into 2 categories - optimistic and pessimistic, or if you will, glass half-full or half-empty. It the same players in either case so it really boils down to what the individual believes. E.g., the TEs were always behind Witten and that was never going to change as long as he was on the team and, therefore, it's truly unknown what they will be when the weight in all on them. The half-empty folks point to their historical stats and are pessimistic, the half-full folks point to recent Witten stats and are optimistic the TEs can duplicate them, either individually or as a group.
In either case, the 32 oz. tankard has 16 oz. of Shiner in it. As for me, I'm simply going enjoy my 16 oz. of Shiner and when that's gone, if I still am thirsty, fetch me another.
