As the possible trade for Shawn Marion comes closer and closer, let's examine what exactly Marion, a long-time nemesis of the Mavs, can now assist the Mavs with:
The guy might just be the most versatile guy in the NBA. His length and speed allows him to effectively play as many as four positions. He is a decent balll handler, can shoot the outside jumper (despite his horrid shooting form), attack the rim, and play around the basket. We saw just how versatile he was during his days in Phoenix, where he was one of the key reasons the Suns were able to play the way they did.
2. Defensive capabilities
Marion is a coach's dream defender. Impressively, he is one of the most versatile defenders in the game. He always finds himself as one of the league leaders for blocks and steals. During his time in Phoenix he was asked to guard everyone from Dirk Nowitzki to Tony Parker in the playoffs.
Marion is an excellent rebounder, as shown by his 9.9 career rebounds per game average. With a possible lineup of Kidd-Howard-Marion-Nowitzki-Dampier/Gortat the Mavs will have excellent rebounders at every position. Opposing teams are going to find it hard to get second-chance points and stop second-chance points.
4. Up-tempo playing style
The Mavs have made it obvious that they want to "Run! Run! Run!" with Kidd at the helm. Marion will undoubtedly help with the running game. Marion loves to play with transition point guards, as evident by his stats when he was in Phoenix with our very own Steve Nash. Jason Kidd is just as dangerous in the open court as Nash, despite his advanced age.
Since "small-ball" is often popular when running, Marion can help with the lineup by playing the four. A lineup of Kidd-Terry-Howard-Marion-Nowitzki is packed with speed and shooting. I can already imagine the alley-oops that Kidd will be throwing to Marion.
The Mavs already have great nicknames like "The German Sensation," "The Animal" (if Bass stays) and "JET." "The Matrix" will be a great addition.
