I will be the first person to admit that the Mets 96 win season (they can still get win #97 today, but with Oliver Perez on the mound, its not likely) came as a surprise to me. I was expecting terrible starting pitching, a lack of clubhouse chemistry, and injuries. My expectations were met: Pedro Martinez had a very mediocre 4.48 ERA in the games he played, and the Mets were forced to rely on a perennial number 3 pitcher, Tom Glavine, to be their ace; Lastings Milledge has not mixed well with the veterans and Pedro's questioned Willy Randloph for bringing him back too soon; Pedro's out for 8 months and Floyd missed significant time. Nonetheless, the Mets were able to overcome all that and win a fairly tough NL East easily. Like the previous NL East champs, I believe the Mets will flop in the playoffs.
Somehow, Orlando Hernandez does not intimidate me as much as other Game 1 starters such as Johan, Barry Zito, and Jake Peavy. While Hernandez has been lights out in the playoffs (2.55 career postseason ERA), I would not want him to be the number one pitcher in ANY playoff rotation. The number two starter is Glavine, the number 3 in all those Braves' division championships behind Maddux and Smoltz. A 5.15 division series ERA from Glavine hardly helped the Braves' postseason woes and I doubt it will help the Mets now. The number 3 and 4 slots will be occupied by Steve Trachsel, the least intimidating starting pitcher in the majors, and 2006 surprise, John Maine. Neither have any playoff experience whatsoever. The pen is good, going from Wagner to Heilman to Chad Bradford, but I don't think I trust Pedro Feliciano or Darren Oliver with a tie ballgame in the 7th inning in game 5 of the NLDS. Could be just me though.
Steve Trachsel, looking very unintimidating
Last but not least, the Mets' offense. Unlike the Yankees (questionable pitching, amazing offense), the Mets are a solid/good group, but are hardly stellar 1-8. Reyes, Wright, Beltran, Delgado, and to some extent Shawn Green are all offensive threats, with Paul LoDuca also having a good year; but after them...Jose Valentin? Has anyone ever been afraid of Jose Valentin? Cliff Floyd in left is yet another injury waiting to happen, and he can't hit lefties worth a lick (.179 BA vs. LHP this season).
Prediction: Los Angeles (or San Diego, though I think the Pads take the West and LA the wild card) takes the series in 4.
