From the comments to the last post:

things aren't getting brighter? With one of the best young QB's in the league, a defense that will improve with draft picks and smart signings, improving depth along the o-line...

When has Shanahan ever shown him capable of making smart defensive signings and draft picks?

How can anybody claim we have improving depth on the offensive line? Our offensive line is only getting older.
