Glavine Comes Back

After getting turned down by the Atlanta Braves Tom Glavine has come crawling back to the Mets.
He agreed to a 1 year, $10.5 million contract. Not sure what that means compared to the option they had, because I thought they were supposed to pay him $7.5 million plus $7 million, if they wanted him back.
Glavine has an option for 2008 if he pitches enough innings.
Now the Mets rotation has Pedro (in June), El Duque, Glavine, Maine and Perez. Pelfrey, Humber, etc are also options.
I still would like to see the Mets get Zito but they probably won't be willing to part with $90 million over 6 years to get him.
