Jason Marquis a Cub?
Bill Madden of the NY Daily News says it's possible:
And very quietly the Cubs have been exploring DeRosa's best friend, Jason Marquis, as a potential bargain reclamation project. Marquis had a horrible season with the Cardinals this year, falling out of favor with Tony La Russa and pitching coach Dave Duncan, after winning 28 games the previous two seasons in St. Louis. But, on his own, he recently worked under the tutelage of a major league pitching coach in Florida and is said to have straightened out two mechanical flaws Duncan couldn't find. Hendry got good reports on Marquis and is strongly considering him for one of the two rotation vacancies.
Depending on the price, this might be a very good signing. DeRosa and Marquis were in the Atlanta organization together from 1999 through 2003.
Have at it.
