I guess my reaction is almost opposite yours, DGL. I'd call Davidson the anomalous game. USC seems more like what I'd expect from this team: not always pretty, and a rotating cast of scorers (though EJ has been looking more and more solid lately), but solid wins against decent teams—and on the road even!
Anyway, just to quibble a bit more with the previous dooming and glooming, according to ESPN, TT is averaging 50% from outside, Teahan 41%, and EJ 33%. I for one am pretty happy with those numbers.
Now, I missed the first half last night (darn birth classes!), but what I saw in the 2nd looked pretty good: Johnson had some great athletic plays, and TRob continues to shine, even against double-teams. Good stuff.
