What's the Difference?

What's the difference between the New York Mets of 2007 and the New York Mets of 2008? I'm not asking for some of the obvious ones, the roster changes and such. What is the difference that will very possibly put them over the top?

1. Johan Santana. Having an ace, a stopper, who goes out every five days is extremely huge for a team in the pennant race. Johan essentially replaced Tom Glavine as the Mets' #1 starter, so the difference from 2007 is huge. (Remember Game 162 of last year?)

2. Carlos Delgado. His miraculous turnaround from a year ago is huge to a Mets' offense that's been without Moises Alou and Ryan Church for most of the year. He is hitting well and hitting clutch and has certainly been carrying the team.

There are a few others that can go in there. Camraderie, better production from the corner outfield spots, better defense, better starting pitching (overall), but I think that Carlos D. and Johan are the two essentials that can make this team win.

Coming Up: Oliver Perez takes on Chris Volstead of the Marlins as the Mets look to increase their lead over the Phils.
