While I agree that Calhoun is deadly from 12-15 and even near the tin and that he has ugly form, he is shooting very well from three this year (air balls or no).
Since 01-02 these are the players that have shot 40% or better from 3 with 20+ attempts:
Caron 40% 01-02
Gordan, 41, 42, 43 from 01-02 to 03-04
Robertson 43, 40 01-02 and 02-03
D. Brown 42 02-03
Anderson 41, 41 in 03-04 and 05-06
Gay 47% in 04-05
Williams 40, 40 in 04-05 and 05-06
Then comes a pretty horrendous shooting slump from the team:
Robinson 42% in 07-08
AJ 40% in 08-09
Giffey 43% in 11-12 (21 attempts)
Obviously his percentage could go up or down from here but from the first four games he's shot pretty well.
Daniels needs to focus closer to the tin, he's been pretty poor from 3 so far.
BTW: Napier now leads the team on 3PT% after Giffeys poor shooting last game, well, only poor for him.
