The Mets dropped 2 out of 3 from the Braves in Atlanta this week.  We learned this team can look very good one day (Monday's 6-1 win), and very bad the next (Tuesday's and Wednesday's beatdowns).Let's see what else we learned.HittingThe Mets lineup pounded out 30 hits over the three-game series, but they failed to capitalize with men on base.  First-and-second with no one out soon became 2 outs with 1 or no runs in.  Sloppy baserunning reared its ugly head once again, with two men getting tossed out at home on Wednesday.  Tim Teufel's decisions as third base coach have been as questionable as his fielding in Game 1 of the 1986 World Series.As a team, the Mets left a total of 21 men on base during their 2 losses.  They're getting on base, but they're wasting too many opportunities.Kirk Nieuwenhuis has been impressive in his small sample size, compiling a .976 OPS in 32 at-bats.  See the boss's piece on whether he should start over Andres Torres or not.Overshadowed by his shaky defense and baserunning miscues (well, really only one), Josh Thole has quietly put up a .925 OPS in his first two weeks of the season.Ike Davis continued to look more like Ike Davis, belting 2 home runs against the Braves this week, and Lucas Duda and Jason Bay showed signs of breaking out of their slumps in Atlanta.  And oh yeah, that Wright guy is pretty good.PitchingDillon Gee did his best Greg Maddux impression on Monday, holding the Braves to 1 run on 4 hits through 7 innings.  But it was all downhill for Mets pitching from there.Johan Santana lasted only 1.1 innings on Tuesday, allowing 4 earned runs.  He emerged healthy, which is still a positive as he makes his comeback from shoulder surgery.  R.A. Dickey got washed away in the rain on Wednesday, saying the baseball felt like a "wet water balloon."  He gave up a career high 8 runs in 5 + innings.  The defense did neither pitcher any favors, but they did nothing to help themselves out of jams.The bullpen was pressed into service early on Tuesday and Wednesday.  Manny Acosta pitched a valuable 3 innings on Tuesday, keeping the bullpen from wearing out - as it turns out, they were needed again before expected on Wednesday.DefenseThe defense continues to struggle.  We learned this will be an Achilles Heel all year long.  Jason Bay looked like Torii Hunter on Monday, robbing light-hitting Jack Wilson of a home run, then proceeded to play left field for the rest of the series as if he was distracted by a spaceship, ala Bernard Gilkey in Men in Black.Even the sure-handed Ike Davis committed a throwing error trying to force out a runner at third on a bunt attempt.The Mets went .500 on the road against NL East teams, so it wasn't all bad.  But it's safe to say we still haven't learned what this team is really going to be  the rest of the season.What did you learn?
