As is the case every season, the Mavs’ success boils down to the health and effectiveness of Josh Howard. Dirk Nowitzki, Jason Terry, and Jason Kidd are rocks, stabilizing forces of consistent production. But Josh has always had a bit of unpredictability in his game, and it’s that unknown factor that puts the Mavs somewhere between very good and truly great. Dallas was gently nudged to the preferable end of that spectrum in Howard’s return against the Suns, as Josh scored 18 of his 20 points in the second half and provided a cornerstone for victory. In this installment of Moving Pictures, we’ll take a look at Josh Howard’s return performance, and assess what it means for the team going forward.
