I mostly agree, given what we've seen so far. But fans have seen three years of awful and then a fourth year of great before. Gary Barnett's first four years at Northwestern:
No Northwestern fan, the summer before 1995, was predicting ten wins. It looked like Barnett's rebuild was going just like all the other rebuilds. And then, out of nowhere, once the players matured, a click.
I'm not saying "that's what will happen for Lovie!" nor am I saying "we're totally sunk". I'm simply saying that the roster is rebuilt and now we get to see what Lovie can do with it.
