If all those things happen, we're an elite team. Last year, we won 20 games against a very tough schedule with a first year coach and a roster damaged by injuries and bad behavior. We couldn't defend or rebound at all by the end of the year... And yet we outscored a few teams at the end anyway.
If Bell or Starling become "breakout stars" that would be huge. Most teams don't have a star... We have two candidates even if you're pessimistic.
Freeman being as good as his high school ratings suggest isn't a long shot. He isn't being asked to be "the man." We have a bunch of juniors and fifth year seniors to take on the load. It works allow his talent to develop slowly through the season.
Moore is probably the tenth guy in the rotation, even if we don't get any more transfers. If he beats out Cuffe, Carlos, Westry, or heaven forbid Starling, that's a good thing. (Or it indicates the roster completely collapsed).
Chance Westry is a serious wild card, I agree. But we aren't really relying on him. We have Carlos, Starling and Cuffe that duplicate his skills, if not his potential impact.
Similarly, if Carlos doesn't adapt to high major ball very well, we still have known quantities Starling and Cuffe, as well as high upside players in Westry and Moore to cover for him. I think at the least he'll be effective at end of game situations and if we need him to help break a press.
Again, a lot can go wrong and we can still have a good season... If everything goes right, we could have a great season.
