Why are the Mavs so bad at shooting?

[MrGoat]

We don't have a single 40% 3 point shooter is one reason. Of our current guys on the team Dinwiddie is the leader but judging by his career numbers expect a regression. A lot of it is just the roster. The way Bullock started the season is another reason as was Hardaway's injury and poor shooting before the injury. And Kidd's higher emphasis on defense may affect the legs they have going into their shots as well
