Well the Mets made a move this off-season. Yes, pop the champagne bottles, take a picture of it and cherish it, because knowing the Mets they won't make too many more moves between now and February.
The Mets hired ex-Yankees hitting coach Kevin Long to revive their stagnate offense that ranked 28th in MLB in batting average and 21st in the league in runs scored. While Lucas Duda had a break out year with the power, 30 homers, and Daniel Murphy was an All Star at second base, the Mets really never hit consistently well in 2014. In fact, they haven't hit consistently well at all the past five years.
Long spent eight years with the Yankees, but he was working with a lot of top flight hitters like Derek Jeter, Mark Teixiera, and even Alex Rodriguez. Hitting coaches are not the "Be-All or End-All" when it comes to putting together a baseball team. Either the hitters on the team have the talent or they don't.
Long was fired this year after the Yankees offense was putrid this season. They were ranked 20th in batting average, 23rd in on base percentage, and 20th in runs scored. He will be hard pressed to get a lot out of the likes of lite hitting Juan Lageras, Travis D'Arnaud, Wilmer Flores, and Matt DenDeker in the near future.
