Is Brook Lopez just joshing or really trying to extend his range?

So what's with that Brook Lopez video of two days ago, the one showing him casually taking --and making-- three pointers from three and four feet beyond the arc at the Nets training facility.

Is it part of next year's game plan ... assuming Lopez is back?  Or just some fun?

Mike Mazzeo thinks it may be part of a game plan. He thinks Lopez as a three point threat has promise. First, he notes the three pointers were part of a workout, directed by big man coach Joe Wolf, that had Lopez work on lefty push shots, then mid-range jumpers before moving beyond the arc.

Mazzeo notes that three point shooting, even for bigs, is at a premium now, pointing to Chris Bosh who went from a mediocre, at best, three point shooter at power forward to a legitimate threat as a deep-shooting center.

Still, he notes, Lopez has a long way to go. He's 1-of-17 from three in game situations.  And, of course, the Nets would like to see him improve his post game. Still, when the Nets needed him late last season, his repertoire --even without a three-point shot-- was hard to beat.  In one 13-game stretch during the playoff run, he averaged 26.2 points, 9.6 rebounds and 2.4 blocks while shooting 59.2 percent from the field and 84.7 percent from the free throw line.
