With pre-season NBA action under way and fantasy competitions about to begin, which centers should your team be drafting?This is the final piece detailing the Top 5 NBA Fantasy players in each position for this upcoming season. Here we're covering off on Centers, but you can view all the fantasy positions and even more here. As I mentioned last week, quality big men are vital to the success of every fantasy roster. As such, fantasy owners should target at least one of last week's Top 5 Power Forwards or one the Centers below early on in their drafts. - Al Jefferson - Over the past three seasons Al Jefferson has averaged at least 17 points on 49% shooting from the field with 9 rebounds. Last season he only averaged 1.1 blocks which was his lowest in seven seasons. This was mainly due to a crowded front court with Enes Kanter and Derrick Favors vying for minutes. Now at the Charlotte Bobcats, Jefferson will be the sole low post presence, best offensive weapon and best defensive big man. At 28 years old and in the prime of his career, Jefferson will have a superb fantasy season and should be drafted in the top 12. Marc Gasol - He may not be the sexiest pick in the earlier second round but he is amongst the very best of the tall timber. Gasol contributes the way very few others can, in fact last season he become only the second player in NBA history to average at least 14 points, 4 assists and 1.5 blocks while shooting at least 84% from the free throw line.The other player? Michael Jordan. Marc Gasol also averaged eight rebounds and a steal per game. With new Grizzlies coach David Joerger looking to increase the offensive tempo and which therefore creates possessions, it's mouth-watering to think how this should improve Gasol's statistics this season. Anthony Davis - Davis's first season was over shadowed by a phenomenal rookie season from Damian Lillard. Nevertheless, 'The Brow' had a discreetly valuable fantasy season. If we concentrate on his post All-Star stats in 30 minutes Davis averaged 15 points, 52 FG%, 81 FT%, 9.3 rebounds, 1.5 blocks and 1.2 steals. That's some solid all round production in anyone's fantasy book. The most important figure in that line for mine though is 30 minutes. With Robin Lopez no longer in New Orleans and Davis a bigger and stronger player than last season, he should see an increase in playing time, particularly at Center, and should undoubtedly improve on these statistics. It won't be long until this number 1 draft pick becomes the number 1 player on this list. Al Horford - Horford has always had the game to become a legitimate fantasy Center star. Last season he went a long way to fulfilling that potential by averaging 17.4 points, 10.2 rebounds and 1.1 steals which were all career highs. Additionally, his 1.1 blocks, 3.2 assists and 54% FG were consistent with previous seasons. With Josh Smith no longer in Atlanta, the Hawks will rely more on Horford at both ends of the court. Pick Horford right after Davis in the second round. Dwight Howard - So you're halfway through the second round of your draft and Dwight Howard's name is towards the top of your draft board tempting you to pick him. However, you know that with 'Superman' comes a big bowl of kryptonite called FT%. Take Howard and there is no coming back from your punt free throw strategy. If there is a season to try it for the first time, or the last time, this season looks like the one. Howard joins the quickest offensive system, a superb pick and roll partner in Harden and a team that throws up threes for the fun of it. So unless you draft Durant, Curry or Harden who give you a significant advantage in FT%, consider Howard for a fun, but frustrating, fantasy season. - Next week I will unveil my Top 10 list of players to target in your fantasy drafts this season.
