Bottom line....
People can be as optimistic or delusional all they want. It doesn't change the fact that we have some major holes. Rebuilding is a process that takes time. There is no magic wand.
Saban may be a great coach, but he is no miracle worker. We have improved only on paper at this point. We'll need to prove our improvements on the field and not on paper.
Some may see my view as non-supportive. The exact opposite is true. If you aren't realistic about your failings, you delude yourself into a false sense of success. Acknowledging and correcting your weaknesses makes a team better. Delusional optimism serves no purpose except for euphoria. You might as well be tokin' with Ricky if that's the sensation you want.
