I'm a Maryland fan and I think Goru's comments are valid. Until today they really haven't played like a top five team. We'll see how it goes going forward. It's not very reassuring to see the Terrapins trailing Temple and Harvard for most of the game.
As Russ said, however, it's hard to know exactly who the starters are, so it might not be useful to imply that only the five "starters" can be relied upon. In fact, I can't remember before today a game where both Ayala and Wiggins were both in the starting lineup (I'm sure it happened, but not often). Moreover, I would contend that there's a lot better ways to evaluate a bench than merely by scoring totals.
The point with Maryland is that there are 4-5 guys on the bench who can come in and provide legit quality minutes while giving the "starters" a rest. I doubt you'll find many basketball people who aren't willing to agree that the Terps have a lot of depth...
