Deron Williams has been shanking frequently. It's been that way for a little while, with Deron going from a .439 field-goal mark in 2010-2011, to a .407 mark in 2011-2012, to where we're currently at with his .382 field-goal percentage in 2012-2013. Howard Beck of the New York Times listed some functional reasons that may account for Deron's shooting woes:

"The source of Williams's struggles is somewhat elusive, but injuries — including a banged-up right (shooting) wrist and sore right elbow — have surely played a role. He also has a left-ankle injury that will probably require surgery next summer. Williams said it is not the bumps and bruises, but his general comfort level, that is to blame."
