It sure does seem like Kidd has attempted a fairly inordinate amount of three's this season, oh he has...
43 of his 89 field goal attempts this season have been from behind the arc.
That number doesn't include all the three's he has tried to take that have been called two's because he has had his toes on the line. With those included it would probably increase the total to over 50 and easily raise the overall percentage to over half.
UPDATE: Here's the NBA leaders in 3PA % with a minimum of 80 FGA's.
